Hi,
I am displaying progress information about an asynchronous file transfer
(using gnome-vfsmm) in a dialog box. However, I am getting very weird
errors from the X Window System:
The program 'duality.elf' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadGC (invalid GC parameter)'.
(Details: serial 233809 error_code 13 request_code 75 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error()
function.)
I tried reprodcing the error with --sync, but that didn't work, the
program will just lock up and no error message at all will show up.
Sometimes I'm also getting this error, which is less verbose:
Xlib: unexpected async reply (sequence 0x71e6)!
I googled for this last error and it turned out that it may occur when
the GUI library is not threading aware or not thread-safe. Can I enable
threading support in gtkmm somewhere? I called Glib::thread_init() but
that didn't help.
Thanks in advance,
Matthias
