Bug 268389

Application: kstars (1.6.0)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-27-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

 I'm trying to control my Losmandy G11 with Gemini with KStars using an USB-to-serial cable; the USB port on the laptop connected to a serial converter which, in turn, is
 connected to the RS-232 port of the Gemini.

 Opened the Telescope Wizard in KStars and chose 'Losmandy Gemini' as Telescope Model (leaving this option to the default 'LX200 Basic' Telescope Model produces the same
 error).
 The date and location had already been set and were left untouched in this wizard. On leaving the port entry blank and opting for KStars to scan for ports, the program
 immediately exits. Manually setting the port to ttyUSB0 does not result in a crash, but I suspect no communication is set up between my laptop and my mount at all, as the
 mount doesn't seem to react to any command issued in KStars.
 (Then again, I don't have any experience in controlling mounts with laptops.

- Unusual behavior I noticed:

 None particular; KStars doesn't hang, it exits immediately.

The crash can be reproduced every time.

-- Backtrace:
