session group crashes

same isse now with 2nd session group. the sessions themselves work ok.

Same on Linux Mint 18.1 'Sarah'. Session group segfaults immediately at start, yet single sessions are OK. Grsync 1.2.5, latest version available in Mint repos.

EDIT: just tried installing 1.2.6 .deb from Debian repos, same behaviour.

Same thing happens on Xubuntu 16.04.

Grsync ver. 1.2.5, latest available in main Ubuntu/Canonical repos.

It now also happens with some SINGLE SESSIONS. I tried hard to find what the difference was between the earlier tests with singles sessions which worked fine and a couple of newly created session which do not work, but could not find anything.

2 kinds of syslog lines:
1) grsync[xxxx]: segfault at xxxx...
2) traps: grsync[xxxx] general protection ip ...

Also I don't know if it could affect the outcome but my destination for the backups are on a NTFS volume (partition). I know there are differences in the way the permissions are handled vs. ext4 but the details elude me. I think some info is lost/altered when moving/copying from ext4 to ntfs. Anyhow that didn't prevent me from doing several successful simulation runs of single sessions with the keep ownership, group, permissions options enabled.
