to upgrade to Fedora 15 I did a clean install. I am using Gnome3 as my desktop.I have installed Meld. However if I go into preferences>editor the following four display preferences are visible but greyed out and I can not find a way to activate them:
Insert spaces instead of tabs
Show line numbers
Show white space
Use syntax highlighting
I have tried reinstalling Meld and python and pygtk2 but it has change nothing. I have tried running meld as root and still nothing changes. Apart from these four options everything works correctly with the program. Am I missing something obvious or should I file this as a bug?
