commit 9322f737819a3d81088699b1d7fa667259245411
Author: Panu Matilainen <pmatilai@redhat.com>

    Don't mess up problem altNEVR in python ts.check() (rhbz#501068)
    - the use of strrchr() silently casts away the const from the problem
      set altNEVR string, which we then happily modify..
    - similar to commit 62cc76e25cdfad78ac30bb28f626b474efdecddc
