I've had a problem with my Sygic Mobile Maps 9 since a few months ago that it occasionally crashes. Reinstalling and, more recently, updating to 10 didn't change anything.
I decided to run it through the terminal to see what's happening. Here's the output:

~ $ /opt/sygic/Drive/Maemo/drive -cwd=/home/user/MyDocs/Drive/Maemo -rfull
> set_stream 'ALSA Playback'
Stack info:

#3 /opt/sygic/Drive/Maemo/drive [0x213264]
Segmentation fault

What's exactly happening and what can I possibly do about it?

Bump... any help?:x

Well, I believe that your installation is somehow broken or something because segmentation fault usually appears when permissions are wrong. So ether you can't read from that location or you can't write to that location or something like that.

Do you suggest I should play around with libc.so.6's and drive's permissions?
What does that stack info mean anyway?

Thanks in advance.

Edit: chmod 777 drive didn't help, still segfaulting.The segfault doesn't happen immediately upon start, it happens only while in certain locations (either navigating or zooming the map). What I mean is I can force it to segfault.... example: zooming in and out of Warsaw. It always segfaults. However, it never happens in Berlin or London for instance.

Edit2: just got it to segfault and display more info:

well, invalid pointer is pretty much what the name suggests. So if this happens only on certain maps maybe your problem is that some of the maps are broken somehow.
How did you install sygic? From ovi? When you were upgrading did you remove everything from v9? First uninstalled V9 and then removed Drive, Res and Maps from MyDocs?

I had a similar error when I first installed Sygic 10 on PR1.3; turns out I was trying to use the program with maps from Sygic 9. It kept crashing out until I re-downloaded the (Sygic 10) maps and put them onto the device.

kinda like broken maps

I've just uninstalled the application, removed Res, Drive and Maps, installed it again and copied the stuff back. Still segfaulting. Could a file system corruption be possibly causing this?

Yes, but unlikely. Have you tried to run sygic without maps? Of course, it will tell you that there are no maps loaded but it should start normally. Or try to find some other maps, maybe those you have are corrupted.
