crash on extract (to sanitize_path when str has no value)

one task is enough

Thanks for your bug. The crash has nothing to do with the libcdda.so warning (which is bug #19383). What version of Ubuntu do you use? Could you get a backtrace of the crash (using bugb-buddy dialog to send the bug upstream or gdb)?

thx sorry - I'm a newbie
 I'm using dapper flight 4

Thank you for working on that. After getting the crash and the "(gdb)" prompt could you enter "thread apply all bt", that will give you a backtrace (ie: the suite of functions used before the crash)

thx here:

I've forwarded the issue upstream: http://bugzilla.gnome.org/show_bug.cgi?id=332638

It seems to chock on some path, do the CD, track, folder used have special names that could confuse it?

Do you still have the problem with Dapper or Edgy?

Bug #73956 is a duplicate of this one and the reporter is using edgy.

could you try if that's still an issue on recent ubuntu versions?

no recent duplicate or comment about similar issues, closing this bug, feel free to reopen if you still have the issue on hardy though
