Hm, I just tried it with Blackbox from CVS which should be more
NetWM-compliant (according to its `COMPLIANCE' file) and get the same
error. I wonder where exactly the problem is.
AFAICS the following lines in esmart_trans_x11.c are relevant:
/* Fetch the root pixmap */
ret = ecore_x_window_prop_property_get(vroot, rootpmap,
x_pixmap, 32, &data, &ret);
if (ret && (p = *((Ecore_X_Pixmap *) data)))
The first error above is thrown if the test in the if-statement
returns false. `rootpmap' is not empty, otherwise this code would not
get executed and AFAICS Blackbox, more specifically `bsetroot' sets
`_XROOTPMAP_ID'. `vroot' is probably identical to `rroot' as Blackbox
does not use `_NET_VIRTUAL_ROOTS'. So maybe `x_pixmap' is the
problem? (All this is just based on looking at the code as I failed
to debug it.)

Okay. Besides I have to say that it already looks very good and seems
to be very resource-friendly.

I'll consider this. (c;
Thank you for your explanations.
