Could you compile with debug information ? Add -DCMAKE_BUILD_TYPE=debugfull to the cmake command line and then do make and make install. If this is the same as the other uncaught exception, the backtraces should be similar with debugfull.
*** Bug 214291 has been marked as a duplicate of this bug. ***
I believe that this is the same crash. I however, don't see any extra information in this report even though I've compiled with debugging enabled. It is very possible that I've mucked that up somehow - how can I check if debugging is enabled for my installation?
