Hi, The kdevelop RC in kde-unstable (kdevelop-3.10.0-1.fc12.x86_64) has plugin loading issues; see error messages below. However, if I download the sources for kdevelop and kdevplatform directly, and build it myself, the plugins are found correctly. If I simply install kdevplatform-devel and build kdevelop by myself, the errors persist. I am not sure where the problem lies. Here's the console output of starting kdevelop (from the rpm): ---------------------------8<--------------------------------------- <unknown program name>(9751)/ KDevelop::allocateRepository: picked duchain directory "/home/rrajagop/.kdevduchain/{aae9945b-f354-4d84- bb4e-64e588a89635}/0" Calling appendChild() on a null node does nothing.
