Package: denemo
Version: 0.7.5-1
Severity: grave
Justification: causes non-serious data loss

Hi,

I tried to use denemo tonight to transcribe some music I had composed.
Unfortunately, the undo/redo feature seems very unstable, and caused the
application to crash (with core dump) after 15 minutes working on my
transcription :-(

I investigated a bit, and found a very easy way to produce such a core
dump :

1. launch denemo
2. hit space bar 4 times to produce 4 C quarter notes
3. hit Ctrl-Z twice, to erase the last two notes
4. hit Ctrl-Y once, which I expect should put the last C quarter note
back on screen but does not (I suppose thinks get bad in memory at this
point)
5. hit space once -> on my machine, I get a floating point exception,
and core dump.
