Version: 3.0.0b1 (using KDE 3.1.93 (CVS >= 20031028), Gentoo) Compiler: gcc version 3.2.3 20030422 (Gentoo Linux 1.4 3.2.3-r2, propolice) OS: Linux (i686) release 2.4.20-gentoo-r8 I created several projects in a row for testing. Java Ant, GBA, PascalGTK, CPPKdeSimple.. The editor context menu holds all items 3x by now, also 'Open with...'.
I cannot confirm this with current KDevelop. IF you're using KDevelop from CVS that was checked out on 4.11. or 5.11., i would suggest you to update from cvs and recompile it. I fixed a lot of context menu stuff arround that days. Poorly there were temporary issues with doubled-menu-items.
Canot reproduce in HEAD
