0.78: 100% of core usage from time to time

[Alt Bass]

It is quite stable overall but sometimes I get dead hang: 100% core usage while no files are accessed.

It occurs from time to time, I have no specific ways of reproducing it. There is nothing specific happening at the time of hang - I only guess that it happens after I assign a colour label and return to browser by hitting ESC or ENTER.

Here is a minidump (generated using ProcessExplorer):

it seems that the freeze comes from view mode and cache... Are you in view mode?

[Alt Bass]

Freeze happened just after I switched to browse mode from view mode, right after drawing browse interface.

Thumbnail.db is 1.1GB.

in the folder do you have a lot of files? only images?

[Alt Bass]

Few images (like 10 of them) and .pp3 files (RawTherapee profiles, like .xmp).

could you try to disable view cache?

[Alt Bass]

What's that?

Anyway, even if I disable it, there won't be 100% guarantee that it is causing the issue because I cannot reproduce the bug repeatedly.
