Explorer.exe crashes every few minutes. sldsearchi

I have started to get "Microsoft Visual C++ Runtime Library" Runtime error in c:\windows\explorer.exe every few minutes. After trying the most obvious things I decided to attach a debugger to the explorer.exe process. The culprit is the sldsearchifilter.dll.

I am not really asking for a solution. This is more of a "field report". Who knows, perhaps it will help someone.
