the downloaded tile is not an image as per its magic number (it is probably an error response webpage returned by the server)
Batch size working... (threads: 29), pending: 8245, done: 286

btw, im using google map and storage as sqlite. Thanks!

Some tile providers don't like batch downloading and return an error pages in place of a tile - which results in this kind of errors you are getting.

This is normally a bug in some application using the D-Bus library.

Aborted

Turning the GPS option off and on again in Modrana did not resolve it nor did renaming the options.bin file

I think I remember somebody reporting some other DBUS related errors though I don't remember how or if it was solved in the end...

Some more things to try:

just running modrana without the sudo gainroot and posting the result (but it works in my case even as root)

reinstalling

Code:

sudo gainroot
apt-get update
apt-get remove modrana
apt-get install modrana

checking if python-dbus is installed (it is listed as a dependency so it should be...)
Code:
```
sudo gainroot
apt-get update
apt-get install python-dbus
```
rebooting and then running modRana (I have seen some mentions of DBUS related out of memory errors like this one in Google search results...)
upgrading to 0.26-3 - no idea how it might fix your issue, but why not

There is no version.txt in /opt/modrana/

I have released V0.26-3 that has the version file and is also build in a more "standard" way.

i just trie to install last version with command line
and apt-get fails too :
"modrana depends : libmagic1 but it is not installable" ....

can somebody help me ?

Well, thats weird - i have checked the repost and libmagic1 is normally available from repos and on device installable.
You can try to run this in the terminal to manually update your repository listing, install libmagic and then modrana:

Code:

sudo gainroot
apt-get update
apt-get install libmagic1
apt-get install modrana

(It happens that the last three turns to my house are under 100m apart, so I get a lot of chances to test it.)

Note that when modRana gets a new voice message while there is already one playing, the new one is skipped.
IMHO your patch only increases the distance - so maybe it just increases the distance for short segments to be larger than their length, so that their announcement is triggered at once when switching to the segment and then being skipped because the last announcement is still playing ?

Thanks a lot in advance !

I have done some road testing the new code:

the new code works good (aside from the above mentioned short segment issue)
some long on-highway segments have announcements too far ahead
This is caused by Google setting the default turn distance too high (I have seen 2,5+ km, which is IMO too much even on a highway).
In extreme cases the announcement might be even skipped due to overlapping with the last one.
generally when on highway (long segments + high speed), more announcements at a varied distance would definitely be handy
I have hacked in some rounding to the voice output (325 meters -> 320 meters) which made it definitely quicker to "get to the point"
Some more advanced rounding might make it even quicker (300..330 = 300, 333..367 = 350, 351..400 = 400, etc.).
