I've been seeing this one for a long time - this is on Irix, built with
gcc, as detailed here:
1. xemacs -vanilla &
2. Options -> General -> Debug on Error
3. select text w/mouse
4. go to another virtual desktop, and soon this appears in *Backtrace*:
Signaling: (error "unrecognized selection-conversion type" nil #<INTERNAL
OBJECT (XEmacs bug?) (opaque, size=4) 0x1063db60>)
this may very well be specific to the Irix window manager (4DWm) and its
strange idea of virtual desktops...
I just noticed that it happens in 20.3 and 21.1.3 (that last one running on
Tru64U but displaying on Irix).
