Trunk version doesn't load plugins?

[Aleksey Midenkov]

When I start stable version (branches: kdevelop 4.6, kdevplatform 1.6)
it is all ok, all plugins are loaded correctly. lsof output for
opt/lib (where plugins are installed):

When I start development version of kdevelop (master branch for
kdevelop, kdevplatform), it seems that it doesn't want to find its own
plugins. This is the only files opened from opt/lib:

I start kdevelop with such command:

export KDEDIRS=/home/midenok/src/kde/kdevelop/trunk/opt
export KDEV_DISABLE_SPLASH=1
/home/midenok/src/kde/kdevelop/trunk/opt/bin/kdevelop

Should it regard KDEDIRS as stable version regards it? I also tried
KDEHOME and got same result.
