Comment 1 for bug 397744

I looked into this issue again and tried rebuilding the package mono-debugger_2.4.2-1 from source. This fixed the aforementioned problem i described in the original report. In addition i had to install the package mono-dbg_2.4+dfsg-5ubuntu1 to make the mono debugger work correctly on monodevelop. I can debug c# applications using monodevelop now.

So this issue might be fixed by rebuilding the mono-debugger package and adding an additional package dependency to the mono-dbg package.
