Well, this looks like a crash in entry_added in indicator-applet as a result of indicator-application sending a INDICATOR_OBJECT_SIGNAL_ENTRY_ADDED signal. Not sure who's at fault yet. The fact that the top frame of the stack trace is missing is bad because it's hard to tell where in entry_added we crashed.

the bug has recent duplicates but they lack the first frame as well for some reason

Michael Terry (mterry) wrote on 2011-04-12:

These traces are uniform but bizarre. They all seem to be during the processing of an ApplicationIconChanged signal, but the stack trace shows the local variables as if it were handling a ApplicationLabelChanged signal, and even shows a application_label_changed() call (with the wrong function signature) in the stack.

But the variable contents and the signal name itself point to ApplicationIconChanged being the actual signal. I think I trust those data points slightly more than I trust gdb's after-the-fact processing of the stack. That combined with the bottom frame always missing points to some stack corruption. It's just odd that it's so uniform across the duplicates.

Progress, I think. Noting that all the crashes are only in classic GNOME and that the signal may really be IconChanged, I looked at what we send on to the indicator-applet when that happens. And I found code that *could* crash, once an appicon goes away and a second appicon changes its icon. I'll file a merge request and claim this is fixed, but the proof will be once we stop getting bug reports about it.
