Can't login using WDM!

[S.Salman Ahmed <ssahmed@pathcom.com>]

Last night I upgraded all X packages to XFree4.0.1, and now I can't
login to X using WDM. Every time I enter my userid and password in the
WDM login panel, the login panel disappears, I see a plain grey
background, and then the login panel reappears.

Is there anyway to debug this problem to find out why this is happening
? And also, is there a quick fix for this ?

I am using Wdm-1.19-4.2, and I noticed the problem right after I
installed xbase-clients-4.0.1 (and xcontrib-3.3.6 was removed).

I'd appreciate any info.

Thanks.
