[Kstars-devel] GSoC progress : QList index out of range

[Jasem Mutlaq]

Adityan,

Commit your code and I'll check your branch tomorrow to diagnose the issue.
Btw, the midterm evaluations are coming up soon, so please try to work hard
in this period as the skeleton needs to be ready by June 26th. Same goes
for Daniel with the Ekos scheduler. I realize you folks have exams, so try
to manage your time accordingly.

Regards,
Jasem
