Same here.

Yep. Here is the backtrace from my core dump in same situation:

While waiting for actual fix, you can disable the assert.
In src/StackingList.cc change line 118 from
assert(it != stack.end());
to
if (it == stack.end()) { return; }
This makes function return quietly if one cannot find proper
position from the stack.
You may get some undefined behaviour with some apps, but
atleast Blackbox doesn't crash.

randomly messing around with unfamiliar code and hoping
that everything will be allright. ;)
