I have the c++0x working draft,
downloaded from the wikipedia page http://en.wikipedia.org/wiki/C%2B%2B0x
in a folder.
When used by nepomuk, it stops at this file and the cpu and memory start to increase.
After one hour, I disable strigi.
I've tried also with strigicmd with the same behavior.
By the way.. It could be nice (if possible) to have some information in the strigicmd showing how much of the document/folder has been processed.
