Recurring crash while resolving

I have some recurring crash while resolving the project.

It's not happening all the time, but often enough to be really annoying.

I'm using usually 2 qbs versions - one on the cmdline (self-compiled) and one from inside QC (usually the one provided by QC)

Especially when refactoring bigger parts or updating the repository to a newer - or resetting it to an older - sha where files which had been part of the project vanish or got newly added this is reproducible.

The stack looks the same all the time, when changing minor (suspicious) parts I only shift the crash to some other location, but the stack still looks similar.

This usually does not happen when I'm using qbs with '-j1' - but this does not make any sense for building.

I can't provide much, but tried to get at least one of the stack traces - see attached log / img.
