Someone else has had this problem in bug #748842 and you can see my response to it in

I don't see any potential workaround for it until we move to GtkBuilder since the issue seems to be in the libglade library itself. Since libglade is deprecated, I doubt they'll be fixing bugs in it either.

Getting this error most of the times:

linuxdcpp: ../../src/xcb_io.c:140: dequeue_pending_request: Assertion `req == dpy->xcb->pending_requests' failed.
Aborted

Using Ubuntu 11.04 version and linuxdcpp 1.0.3 or core version 0.698.

Kindly post a possible solution.
Thank you.
