-- Information about the crash:
Created a script that uses wl-copy and wl-paste a lot (i.e. a tens of times per
second) by sending and receiving a lot of data (about ~100K). That script was
running fine for a few seconds and then plasmashell started crashing. Until the
clipboard got cleared, the crash was reproducible on every single copy->paste
operation.
I'm still not able to create a 100% reproducible case, but posting this in
order not to lose the traceback.
The crash can be reproduced sometimes.
