OFFTOPIC!
Imagemagick regisrtiert einen Signal Handler und der fängt dann alle Segfaults ab, die innerhalb des VDR-Prozesses passieren. Der Segfault muss also nicht zwingend in dem Plugin passieren, das Imagemagick benutzt sondern kann in einem anderen Plugin oder VDR selbst passieren.
Das ist aber nicht gerade schön, oder?
Das sollte kein Programm - das nicht völlig standalone läuft - machen.
Damit ist ja dann das komplette Fehlerhandling nach imagemagick für die Katz. 
Reproduced, will watch it.
In detach mode softhd* plugins use a dummy osd, and CreatePixmap returns NULL.
Skinflatplus fixed, patch attached.
I tried the new git commit, but had to add several additional checks to prevent crashes on startup: fix_nullptr_check.patch
This covers only the displaychannel osd, if other osd menus are accessed while the frontend is detached, there will be other places where a nullpointer is dereferenced...
Did you actually have any crashes on startup?
Draw have empty function in dummy osd mode.
In detach mode softhd* plugins use a dummy osd, and CreatePixmap returns NULL.
i wonder if it is not possible to let CreatePixmap recognice attached mode. Or can shd tell the skin that iit is in detached mode.
In fact, the output plugin tells the skin that if no pixmap has been created, then there is no OSD.
Fixed.
