That's very useful. I will attempt to reproduce this and patch it as
soon as possible. Thanks for the stacktrace.

The best place for bug reports and stacktraces is bugzilla. Please could
you open a bug report for this?

http://bugzilla.gnome.org/

I will try to look into it as soon as I can. I have pencilled in a
couple of days in the next week or two to do as much triaging of old 1.1
bugs as I can and see about making a minor release to buy a little more
time while preparing for v2 :) I have neglected gtranslator maintenance
for quite long enough now.

Thanks,
