i run Citrix daily, and just now i'm getting crashes
with the X server, induced by Citrix client(ICAClient,
running wfica program).

this happens with fglrx, but not with radeon driver.
i run Fedora 7, kernel

Fatal server error:
Caught signal 11.  Server aborting
also, the wfica Citrix window has garbage colors. the
window is hardly legible; and after a short time, the X
server dies.

any ideas? thanks!
