A bug fix release 2.6.1 has been released in June. changelog from website says: Fixes * Segmentation faults with PowerTOP2.6 reported by Julian Wollrath <jwollrath@web.de> * Packaging issues reported by Julian Wollrath <jwollrath@web.de>
We are not affected by either issue, mostly because the segfault wasn't actually fixed in 2.6.1. Please wait for 2.7
