solution: run all qrunners seperatly to get an idea at which part the problems occurs.

here the error occured with ./qrunner -o -r VirginRunner? and ./qrunner -o -r BounceRunner?

after looking at one of the *very* few postings on this issue at http://mail.python.org/pipermail/mailman-developers/2003-August/015525.html a closer look at the files at ../mailman/qfiles/virgin and /bounce made it clearer: some *.db and *.pck were not readable, thus corrupt.

delete these files, and re-run qrunner

in this special case i had to delete all files at /shunt and /bounce ( ./unshunt didn't help)
