Ticket #76 (new Bug)
Bad root window with vncserver

Description
If I try to run e17 under vncserver I get a segfault in xrandr because the root window passed is invalid.
I traced the error all the way back to the roots array in the e17 startup contains an invalid pointer (always 0x25 here)
This roots array is filled from ecore_x_window_root_list() but I don't know enough X to be able to understand what is going on in this function.
Can others reproduce this please? (Xrandr and vncserver are both the latest debian versions)

I get a crash dialog each time I run e17 in vnc.. The recover (F1) does not work.. Xrandr does not work - it says extension RANDR missing on display :1 - do I need to configure anything?
this is a test

I can confirm that this doesn't work. But E is handling the issue correctly, but Xvnc sagfaults.

I'd suggest to move priority to Normal.
