It looks like the latest changes of eqmod (or indi telescope?) introduced fatal error to the code. You cannot unpark a mount, slew, track or goto. The client just freezes at any of these operations with no debug info returned by indi.
OS Ubuntu Mate on Raspberry Pi v2
INDI version 1.1.0+r814.221~ubuntu15.04.1
indi-eqmod version 0.2+r68.221~ubuntu15.04.1
kstars-bleeding version 5:15.04+r5191.213~ubuntu14.10.1
Nope, it was yet another launchpad debian package voodoo. Sometimes the package (indi-eqmod or any other) being built get messed up somehow by launchpad. Anyway, a newer version is available that works OK.
