every 5 seconds to my phone appears:
internal error. Application 'Calendar' closed

I am getting this several times a day now with Conversations and with the email application.

I get a message like: 'Internal Error. Application 'Conversations' closed.'

It's really irritating. Always seems to happen right after writing a long text message or email. Seems maemo is pretty buggy. May switch over to Android, can't stand it if the device can't work in just a very basic way.

I hit this problem, but managed to fix it....

After lots of trial and error I tried experimenting with the keyboard settings and disabled auto-complete. The crashes stopped.

I then started up "Auto completion editor" (in extras-devel). This told me my auto completion directory was corrupt (truncated). I clicked save to store an empty auto-complete dictionary

The crashes have stopped :-)

Hope this helps
