Canon 20D exposure time - by: Herrhausen

Hi, my 20D can't do exposures >30s anymore. When I attempt a 60s exposure the shutter closes after 30s. Then nothing happens for another 30s and after that the frame is downloaded and shown in Fitsviewer. The 20D's dials had been set to "M" and "bulb". Build: 2018-11-15T10:52:54Z

The logfile shows:

Obviously shutter speed "BULB" should have been selected instead of 30s. The "force bulb" enabled or disabled setting has no effect on this.
