Reproducible: Always
Steps to Reproduce:
1. Start krunner (Alt+F2)
2. Type "2^1" (without the quotes): it works OK, returns 1 and shows matching
files, etc.
3. Add a 2, i.e. type "2^12": krunner crashes (sometimes before showing the
result, sometimes after)
4. To get the backtrace, kill krunner and run it through gdb, then do the above
steps.
