+Summary: svn head - segfault in the runtime while running mojoportal 2.x
+
+Current svn head of mojoportal (the 2.x branch) fails to run with current
+mono svn head. I have no idea how to create a test case smaller than
+mojoportal itself, since I cannot gather enough information about the bug
+to find an anchorpoint within the mojoportal/mono code (my lack of
+intimate familiarity with mono runtime internals doesn't help here
+either). Here's a set of gdb backtraces, all occurred while running mono
+on Ubuntu/feisty, amd64, libc6 2.5, kernel 2.6.20-rc3-mm1:
+
+Program received signal SIGSEGV, Segmentation fault.
