I use kde 4.3 rc3 and has enables strigi file indexer.

After resuming from suspend or hibernate, I am always getting notifications from Nepomuk.
First Its says "suspending strigi indexing to preserve system resources"
then after a few seconds its says "Resuming Strigi file indexing".

Then again after few seconds it goes back to suspending this goes on for ever until I logout or restart.

This happens only after I do a suspend or hibernation in my laptop.

This is most likely to be a bug, especially since it is reproducible. Please report it at bugs.kde.org if it does not already exist.

It is a bug (confirmed by myself in IRC after a discussion with Sebastian Trueg and Kevin Ottens), and easily reproducible. Please post it on bugs.kde.org. Notice that to make sure it gets fixed, some testing is in order (I couldn't because I had no disk space to install debug packages).

I filed it against nepomuk don't know if that is the right component.
