Admittedly, there isn't much that can be done about this at present -- but,
I just tried to attach a 500 MB PDF to any message, and Trojita chewed up
100% of one of the cores for a few seconds before crashing. Unfortunately,
I'm running a virtual machine which is occupying a lot of RAM, so apport
told me there wasn't enough memory to produce a crash report :(
I relaunched trojita and I tried again, and it was fine. Slightly different
steps:
First time (crash):
1. Fill in To, Subject and message body.
2. Click Attach, navigate to the file and click okay in the file dialog.
3. The file dialog did not disappear. Crash after a few seconds.
Second time (no crash):
1. Fill in To.
2. Click Attach, navigate to the file and click okay in the file dialog.
3. Fill in Subject, message body, and then send. No problem.
Probably a freak occurrence, but maybe somebody can speculate as to the
cause.
