Hi Andrew,

yes, I'm afraid you are right - right now the 0.4.x branch doesn't
look very stable. There has been a lot of feature development between
0.4.x releases that IMO should have been done on 0.5.x (for future
releases I plan to do _only_ bugfixes on the stable branch). Could you
please create a bug report in bugzilla? I'll look at it after the 0.6
release (in about a weak or so).

Originally I wanted to abandon the 0.4.x branch but I'm afraid that
because we are late with the 0.6 release, all linux distributions have
grabbed the latest release of the 0.4 branch so I'll do some
maintenance for it too.

Thanks,

Jiri
