Kstars crashing

[Wolfgang Reissenberger]

Hi Jasem,
yes, it’s the latest one. Maybe that my setup is slightly special, since I have my mount and the focuser running on a remote INDI server, while the cameras for imaging and guiding are attached to the local INDI server where Kstars is running.

I‘ve seen Kstars crashing at exactly the same position where the status light of the mount is set. But there is nothing special there, no clue why a segmentation fault occurs here.
Any ideas about this?
