Here's my current debdiff and gdb backtrace (as complete as I can get it; something in Thunderbird is preventing from seeing the entire stack). It seems we might have tripped a pango/fontconfig bug, as it seems too deep in the pango stack to be a bug from thunderbird. Googling around reveals this gem of a bug report: https://bugs.maemo.org/show_bug.cgi?id=3150
Since I'm currently building thunderbird -O0 to help improve backtraces, its possible I'm tripped the bug reported in maemo. I'm currently rebuilding TB2 with its normal optimization settings to see if it changes anything.
