I didn't encounter this myself, but got this backtrace. According to the reporter, it's 100% reproducible for him on opening an external device by

   KRun::runUrl(Solid::StorageAccess::filePath(), "inode/directory", this);

I recall claims about crashing dolphin+terminal, but not whether it's been a bug, a mail or some forum.
