            Bug ID: 140908
           Summary: shlxthdl.dll Libre Office Column Handler crashes
                    explorer.exe while previewing TIFFs first time
           Product: LibreOffice
           Version: 7.0.4.2 release
          Hardware: x86 (IA32)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: LibreOffice

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

Additional Info:
Version: 7.0.4.2 (x64)
