Notices

I also have the same problem. I did:

apt-get install libgcc1
apt-get install libc6

After that my calendar permanently crashed. I removed the dashboard widget but still got the message. I had to uninstall the calendar to get rid of the message. The good thing is: you can reinstall the calendar. The bad thing is: Then you will get the error message again. I have read a few posts saying that importing all the your calendar events might fix the problem but I didn´t have the time to figure out how (...with a crashing calendar).
Seems like libc6 still has some incompatibilities. libc6 resides inside the dev-repository, right? That might explain a lot.

UPDATE:
I just installed the OS upgrade via Nokia Software Updater which virtually killed everything I had previously installed. Calendar is working again and I haven´t got any error messages so far. What bugs me is that I have to reinstall every single package now. But there are many ways to cover that.

It's unfortunate that some core binaries have debugging symbols disabled, else we could solve sigsev issues on-device with gdb.

I started getting this problem earlier today after the n900 reset itself while gPodder was downloading. I reset afterwards when I got to work and noticed that user had become read-only and started getting this error along with a lot of error messages about being out of storage (file manager reported several hundred MBs free). I tried several different things that might have caused the problems without luck.

Re-flashed the device, both errors are still occurring and I am unable to restore a backup because of the out of memory error.

It almost seems like permissions issue affecting tracker as the media player isn't picking up on files. Could a permissions issue persist through a re-flash, and could that make tracker and calendar break?

Did you also reflash the embedded MMC? You've got stored cache files that aren't wiped after flashing flashing a FIASCO image.

When I had this issue, I 86'd the calendar database, rebuilt it and then imported it. Worked after that.

I couldn't find instructions on that, is that what the --cold-flash option does, or is there a separate image file that I need?

Found it, thanks. It seems to have worked.

Have the same issue with the clock instead of the calendar (which I had also, but only twice) and it seems that this only occurs after going online so blaming the timezone update seems to be a good bet.

I have the same problem with the internal app error for the calendar, but also at the same time getting the 'device mem. full unable to send\recieve sms' notice.
I reflashed just 2days ago to solve the latter, yet here it is again!
I'm on the edge of getting rid of this device as i seem to be spending half my time just trying to get it to work properly!
Regardless,has anyone got any fixes??
Cheers

DeLoad and TheBurek. You two have helped more by saying what you did. I also installed a updated libc6 before I ran into these problems. I also did 'apt-get upgrade -f'... then proceeded to reboot to run into this calendar problem. I've submitted a bug report with more details here: https://bugs.maemo.org/show_bug.cgi?id=10850

If anyone else has info on what they did that led up to the cause of the problem, we may find a solution to fix it... or atleast prevent it from happening again.

Thanks for posting everyone!

Can you show the steps you took for this?

I have a similar issue, but this is for the settings. What triggers this error is by switching the notification sounds in profile. After a few switches the error would come up, but it will say for settings. Then it would close the window, but the error only happens when switching the sounds in profile.
