I get a crash in src\plugins\qmakeandroidsupport\qmakeandroidbuildapkstep.cpp when I'm trying to open the qmake project that was previously configured for Android (so it has .user file).

The reason is that androidPackageSourceDir is called and pro->rootProjectNode() is null there.

I can fix it with

// QmakeProFileNode *root = pro->rootProjectNode(); 
if (!root) 
return Utils::FileName(); 
const QmakeProjectManager::QmakeProFileNode *node 
= root->findProFileFor(proFilePathForInputFile());

but I'm not sure why is it called at all. So probably it should not be called during project opening.
