Description Francis Herne 2017-09-26 21:04:47 UTC 
Crashed with 5.2-git 836545d after opening two different CPython source trees in the same session.

This is very strange.

cachedSearchPaths is always initialized - it's a static member - and all operations on it are protected by a mutex (see https://bugs.kde.org/show_bug.cgi?id=353309).
