NetBeans 6.5 on Fedora 10: no {}

If you prefer to install NetBeans 6.5 directly from netbeans.org instead of NetBeans 6.1 packaged in Fedora 10 (if you need GlassFish for example), you may encounter a rather annoying bug: it’s impossible to type the {} signs on some keyboard layouts.

I don’t exactly know what it’s related to, but it’s a known issue at Ubuntu and there is a simple temporary fix available. It seems to happen on non-US keyboards only and I have no idea what this “XMODIFIERS=” ./netbeans” parameter does. Should I file a bugreport somewhere?
