I can't reproduce this in a current devel version. Can anyone give additional hints?
I observed that a few times in the realname field but in other fields too. Scrolling the window of the browser (or resizing it) made the garbage disappear. I never managed to "store" this apparently encumbered field content in the user.auth.php file. Each time it appeared it was impossible to reproduce it.
So this is a problem of a garbled display? Not a garbled storage?
It's garbled in storage, I haven't had time yet to try it out with the current devel though.
Is this still an issue in the latest RC release?
Just tried out with the latest RC release - I'm happy to report that saving user names workes flawlessly now.
Thank you very much, IMHO this issue can be closed.
