ubuntu 15.10 + kstars bleeding 2.6.0

Strange behavior of the QSI driver. As from the log below, it connects to the QSI camera, apparently without problems. But then it immediately crashes - as reported by a kstars pop-up warning. And of course buttons of the control panel do not perform any action (except disconnect).

I kept both system and indi updated, rebooted, but no change.

It works fine here. Please try to debug the driver

The crash is still there. I tried to launch the debug version by gdb and I get the following output:

then it stops. Log for kstars in verbose mode is below (I just try ekos with telescope simulator and QSI ccd). Note at 21:50:26.924 the stderr EOF (is that normal?) followed by a restart #1...
At 21:50:26.924 is the last communication from indiserver probably when I get the alert that qsi driver crashes. The following line I click on the "disconnect" button of the qsi control panel...

2016-06-12T21:50:32.575 - DEBG - QSI CCD is disconnected.

I'm on Linux 15.10 and I keep indi synced to the last version....

I see you are running from /usr/local, did you compile it yourself? If you're using the PPA, make sure to delete everything in /usr/local/bin, /usr/local/lib, /usr/local/share, /usr/local/include

ok, that's right there was a confusion between ppa and recompiled version, I got rid of both, reinstalled the whole indi and kstars distribution + dependencies and retried.

No improvement. I just note that in addition the system log by the dmesg command records the segmentation fault of the driver:
[42643.735891] usb 1-1.2: Product: QSI 600 Series Camera
[42643.735893] usb 1-1.2: Manufacturer: QSI
[42643.735895] usb 1-1.2: SerialNumber: 00601295
[42676.925427] indi_qsi_ccd[18530]: segfault at 1 ip 00007f9aba8e5462 sp 00007fff561048f0 error 4 in libc-2.21.so[7f9aba897000+1c0000]

I decided to upgrade to Linux 16.04, thinking to a problem with the libc library. I was really thinking that starting from scratch would help. But no, nothing changes and the crash occurs as before.
I found the "crash" log that I attach here - but its interpretation goes beyond my level of understanding

from /var/crash/_usr_bin_indi_qsi_ccd.1000.crash

Jasem, this looks exactly the same as on Mac. It does work with AstroImager built-in driver and doesn't with INDI driver. The only difference I see is that the first one uses FTD2XX while the later FTDI. Maybe check this. Peter

It was traced to an SDK bug which is fixed now (with help from Peter). So hopefully it will work in the next daily build.

Very good news thank you!

Tested, I confirm that now it's working perfectly again!
