Description jwlhlm 2021-03-09 08:19:51 UTC 
Description:
If I use explorer.exe to preview TIFF files for the first time, explorer.exe crashes after appr. 10 files. I tested the shell extensions with shexiew.exe and found out, that the issue is caused by the LibreOffice Column Handler (Vers. 7.0.4.2). After disabling it, everything works fine again.

Steps to Reproduce:
1. Open explorer.exe
2. Change to directory with TIFFs
3. Preview TIFFs (large symbols)

Actual Results:
explorer.exe crashes. It closes and reopens again. The preview generation is stopped and has to start again.

Expected Results:
All the previews in the directory should be generated normally.


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes

In 7.0.5.2 it is now the "Thumbnail viewer" of that dll, that crashes explorer.exe. "Column handler" seems now working fine (checked again with ShellExView by en-/disabling the functions).

To be honest, after several version changes of windows, libre office and other softwares on my computer, I'm not sure anymore, whether libreoffice is the (only) culprit. So it's ok with me to close this bug report, since I can't reproduce it  anymore in the same way as in the beginning.
Thanks for your work on that annoying issue.
