Please provide a backtrace. See [1] for instructions.

strace of gwibber

Using gdb as in your instruction link did not work because gwibber is a python skript and gdb does not recognize the format.
So this is a strace. I hope it will suffice.

Sorry, it wasn't obvious from the strace output where the problem is.
However, I can help you out with getting the backtrace, which seems pretty important since this app is managing to cause python interpreter itself to crash. BTW in order to get useful info, you'll probably need to recompile python with debugging turned on (use '-g' in CFLAGS and 'splitdebug' in FEATURES -- link about backtraces has more details).

A nice way for running scripts in gdb is the '--args' flag to gdb (which is mentioned in 'gdb --help' message but not in the gdb man page...)

gdb --args <interpreter> <full path to script>

In your case, that should be:

gdb --args python /usr/bin/gwibber

gwibber backtrace

Thank you for the information.
Here is the trace.
I do not know how it is supposed to look like, so let me know what else you need.

Comment 5 Norman Rieß 2010-03-10 08:58:01 UTC

This seems to be fixed with the new python-webkit version.
