I have received this request from a member of the Synaptic team regarding a bug in version 0.42:
If you are using debian, can you please test synaptic 0.43pre3
I want to release 0.43 as fast as possible as 0.42 prints this anoying
stuff and has a minor sort bug left. So please test it and tell me if
it works for you!
If you get the chance, please test it and report your results here (I use SuSE so I cannot help with this).
