Howard, can you try this patch? I don't crash myself, with or without the patch...

Ok, i started crashing now - e.g. bp-b6ec551c-9adf-11dd-880b-001a4bd43ed6

Thanks, the fix works for me as well, and sorry about the previous confusion.

magnus: please try spelling empty correctly...

Today's nightly, which includes the fix, no longer crashes for me. -> verified

Bug 460484 has a test case for this, we should try and set something up in unit tests. I had a look but I couldn't see an easy way of getting into that part of mime. Maybe David has some ideas for how to get into the mime interfaces.

This FIXED bug is flagged with in‑testsuite? It would be great if assignee or someone else can clear the flag if a test is not appropriate. And if appropriate, create a test and plus the flag to finish off the bug.
