This is an issue with the different exception handling used in GCC.
Our toolchain uses the old sljj exceptions while the one you are using
uses dwarf. But this shouldn't be an issue unless you are mixing c++
libraries.  Are you using QtGStreamer? How are you building it?
Can you please describe the steps to reproduce the issue such as which
project should we checkout and which branch, configure options, etc...
