As written by Thomas Schmitt:
I just commited a bug fix (written before i got those drugs) which
would be of interest for the stabilized libburnia-1.2.2 of Debian.

The fix is worthwhile, because the bug is nasty albeit rarely occuring.
I encountered a SIGSEGV by dereferring NULL, but it could have been any
other random stack value instead. So the bug has some potential.
The risk of introducing regressions is low.

See: http://libburnia-project.org/changeset/4809
and - if not too inconvenient - the small beautification of

The adjusted patch against 1.2.2 is attached.
