Hi,
Please find some more informations about this bug. I compile the last
cvs version of e17 today, and the good thing is that it seems a big more
stable when xmms is running. I needed to spend some time to crash e17
today, but it was still possible. The good point is that I have
debugging informations and I had also the window indicating that e
crashed thing I didn't have before. The debugging informations are
included in the attach file. Unfortunately some of the variables are not
accessible.
This time this problem arrives when I press ctrl+a combinason with xmms
playlist open.
