I've been trying to catch this one for a while. It's a wily little critter that tends not to trigger when you are looking for it. I have found one way of reproducing it at will, although it might take several goes. I have attached a backtrace. Others have reported it. No one has managed to get a useful bt, until now.
Sometimes when bringing up the Applications menu, E will segfault. If you hit the restart button, then you are no longer running from your home directory, but what ever directory the icon it crashed on happens to be in. I had discussed this one with raster and others in the past, our conclusion was the some graphics library that is handling the loading of icon files for us is changing directory while it loads. Somehow, things get screwed, and the next time it tries to load that icon, it crashes after the change of directory. I have never seen it hit when just running E by itself. It seems to require starting up, and maybe closing down some other program. Seems that the program being run is important, a couple seem to be really good at triggering it. It never has hit me when running E under gdb or xnest, or the combination of the two, I caught this one by attaching gdb after the crash. The way to reproduce it involves a specific distro (Ubuntu), probably a specific version of the distro (Edgy release with all updates), and at least one specific program. Synaptic can cause it to crash I think. Globulation 2 is good at causing it. I'm going to bed now, others can have a look at this and see what they come up with. It's likely that the only useful answer we can get out of this is "don't run synaptic and globulation on ubuntu edgy".
