This is the log file created by Krita.

SUMMARY
***
When I rename an existing tag, such as "Paint" to "0_Paint" Krita crashes. 
***

This could also be because I have multiple bundles associated to a particular tag before renaming. These bundles were imported through the resource manager. The crash still occurs after clearing old paintoppresets and the Sqlite cache file.

Hi, Hologram!

Could you please attach the Krita's crash log? It should be located at address:

%localappdata%\kritacrash.log

I cannot reprodute the issue here locally, neither in Krita 5.0.6, nor in Krita Nigthly. This crash log would help be identify the problem

Hi Dmitry,

I tested the same procedure on Krita 5.1 Beta 1 and it still causes a hard crash for me. The log file is added.

Hope this helps!

Hi, Hologram!

Thanks a lot for the crash log. The problem looks a bit more clear now :)

Fix a crash when renaming a tag

There were multiple problems that caused the crash. Under some
circumstances, including wrong tag cache value, the tag chooser
widget could try to dereference a null pointer.

(the patch still doesn't fix the issue of the renamed tags
reappearing after Krita restart, but that is a different
issue)
