It turns out that the below patch from 2007 has broken it. Now if
anybody knows where the mailing list archive has gone and how to
find the thread related to this patch ...
For the time being you can circumvent the problem by removing the whole
if (
FCheckIfEvent(
dpy, &dummy, test_withdraw_request,
(XPointer)&args)) {
...
}
from HandleMapRequestKeepRaised.
