"Take Snapshot of Process State" consumes all available disk space

I clicked on the "Take Snapshot of Process State" button while debugging and shortly after I saw some output in the application output:

target file /proc/14470/cmdline contains unexpected null characters

Then Creator immediately becomes unresponsive and eventually crashes. ncdu shows that /tmp is now 20gb larger, which was all of the remaining space on my disk:

mitch@mitch-ubuntu-18:/tmp/QtCreator-cdKsPL$ ls -lh
total 21G

-rw------- 1 mitch mitch   0 Dec 14 08:24 qmlprofiler-data.cZPcBi

I deleted the temporary directories to get the space back, but it seems that I've lost all of my manually configured Qt versions at some point because of this issue. For some reason, my kits are untouched (besides no longer having corresponding Qt versions in most cases).
