Comment 61 for bug 67188

I have the feeling that this bug here might be a collection of several distinct issues, which all look the same due to lack of precise error messages. I filed bug #328980 asking for error messages to be displayed to the user.

Until then, you might use the attached script to learn more about this kind of error. Download it, and then call "sudo bash DownloadedScriptName install" in order to install a wrapper around xkbcomp. Then reproduce the issue, and have a look at /tmp/xkb.*/* for more details about xkbcomp invocations, especially /tmp/xkb.*/err for standard error messages. Once you are done, you can invoke the script with "sudo bash DownloadedScriptName uninstall" to remove the wrapper and "sudo bash DownloadedScriptName clean" to delete the collected data.

With such a wrapper, you can get additional information, like shown in bug #327963 for my own Mac-related issue. Maybe with this information it becomes possible to distinguish the different causes of xkb error messages, and address them appropriately.
