Loading nodelets and nodes in the same launch file causes LibraryUnloadException

edit

I have made a launch file that loads three nodelets (all are properly compiled and loaded), but when also loading a regular node, killing of the roslaunch process with Ctrl-C terminates the program, but also throws a LibraryUnloadException.

terminate called after throwing an instance of 'class_loader::LibraryUnloadException'
 what():  Attempt to unload library that class_loader is unaware of.

When the last <node> tag is removed, no such error occurs.

<launch>

Can someone explain this behaviour?
