Need help. Google finds http://tracker.xemacs.org/XEmacs/its/issue650 which seems to be related (same error message): --- begin cite --- So what can you do? Complain to your distribution that (a) libXt doesn't print the list of missing charsets, and (b) libX11 + libXt require a charset for your locale that is not provided by any font in an xorg-x11-fonts-* package (and, in my case, is highly unlikely to be needed by any user in the locale). --- end cite --- To investigate, we should: 1) try to get more information. Certainly it would help to know if "LANG=C gv somefile.ps" also prints warnings... In that case we would know that it is locale dependent. Perhaps the reporter will tell us. 2) try to reproduce it 3) try find a patch that prints the list of missing charsets. Compiling a patched libXt shouldn't be too hard after having the patch. I cannot find the link again, but some people having had the same error message on other programs think that this might be problems of the x,org server. For that, the missing font would help. Then one can verify be hand whether it is installed or not. Possibly we can find out which fonts are used on CentOS resp.RHEL, where it is working. BTW: When I did test for the original bug report (which is now closed) I started with a minimal fedora 13 installatation as provided by my cloud server. After (IIRC): * yum groupinstall kde * yum install gv and for the remote login: * yum xorg-x11-xauth * yum localinstall nx-client nx-node nx-server (all 3 from www.nomachine.com) I could reproduce the font problem (using the old gv version with international mode enabled by default). But of cause I got several errors from kde (pulseaudio not running etc.) * yum install font didn't help, which I cannot understand: On CentOS 5.5, I do not get any warning at all - so I assume there is no warning on RHEL 5.5. After all chances are there that we can reproduce it.

I've tested on my remote server (which is in the cloud, I do not have physical access to it. So I cannot test without nx on it). I could reproduce the problem (see my other mail), this time with an up to date GNU gv. "git bisect" told me that commit "d3dcb7" causes this warnings. So every GNU gv release since 3.6.8.90 is affected, not just the most recent one. We really need to know which font is missing... Greetings Markus

It may help (but I do _not_ think it's a good idea, as it will completely break international mode) to remove XtSetLanguageProc(NULL, NULL, NULL); from main.c.
