Bug#546887: python-brasero: Segfault in brasero_caps_find_link_for_input at brasero-caps-plugin.c:61

Wed Sep 16 08:57:15 UTC 2009

Package: python-brasero
Version: 2.27.3-1
Severity: normal

Hi,

Here's the single liner which triggers a segfault:

  $ python -c 'import braseroburn; braseroburn.SessionCfg()'

gdb backtrace is attached.

This only occurs when python-brasero *and* brasero are installed. It
looks like python-brasero makes use of the plugins that brasero
provides.

Cheers,

Andrew
