--- Comment #2 from mac-wang at sjtu.edu.cn ---
Dear Mz. Nabet:
  I have applied the contents in
https://wiki.documentfoundation.org/QA/FirstSteps. I had my user profile
restored, but sadly this bug happened again. Also, I can be sure that this bug
is not concerning OpenGL or OpenCL, since I was not using Calc and I am also
observing this bug with OpenGL off.
  I have not tried the second method (export SAL_USE_VCLPLUGIN=gen). However,
this time, a new and "useful" backtrace log had been generated. From the bug
report, I can guess that this bug is somewhat related to Qt5 and/or Kf5 (I'm
not a programmer myself so forgive my mistake). The newly-generated bug report
is attached below.

[Backtrace log]
