Version: 3b1 (using KDE Devel) Installed from: Compiled sources File -> open refuses to open files i.e. via ftp:// or http:// telling me, that i can only open local files. Using File-Selector i can successfully open remote files in katepart and qEditor. Using remote files is interessting, if i want to hotfix a file on a FTP-Server or if i want to transfer partial content from a local file to a remote file. Consider that KDevelop supports developing PHP-Scripts. I would classify this as a bug, since one part of the program (File->Open-Dialog) disables me to do something, that another part of the program (File-Selector) can do fine.
Fixed in CVS. :)
