Running sce-debpurge first run produces an error (forgot to paste), 2nd run no error. Only way to reproduce, therefore, is to reboot and run sce-debpurge again. The error appears related to line 34 of sce-debpurge:
DEBINX_SECURITY="/etc/sysconfig/tcedir/import/debinx/$DEBINX_SECURITY"
Appears to fix:
DEBINX_SECURITY="/etc/sysconfig/tcedir/import/debinx/"$DEBINX_SECURITY""
