-- Information about the crash:
I unplugged my USB and it caused the system to crash. I can't know for sure
what caused it. I was running WoeUSB on it, which stalled at some point and ^C
didn't kill it so I did it myself. I was playing TF2 and decided to unplug it,
when it brought down plasma shell with it.
Looking at the stack trace, there was some heap corruption at some point that
caused a malloc to freak out and kill plasmashell, and I believe the trace
shows it was running the detach code at the time so it isn't some coincidence.
I don't know for sure where the heap corruption came from.
The reporter is unsure if this crash is reproducible.
