Ahh, good to know. Do you know the SVN revision when you commited the
changes? I skimmed the ChangeLog (using svn log) but could not find it.
THis is somewhat important for me since I need a working version in
Mandriva including your other recent fixes for my project very soon.

It would be a bit of a pain to manually patch my old (working) sources
to include your fixes for tickets #187 and #104.

Best
