I still have this problem, however I've found out that it never occurs when I don't have my QuickCam Communicate MP/S5500 USB webcam plugged in, regardless of what other devices are plugged in. I can always reproduce the problem by plugging in the webcam, then going through 2 or 3 sleep (STR) cycles. I had thought the problem was solved, because I had unplugged the webcam. I noticed today that Kaffeine is also similarly affected to Dolphin and Kwrite opens without latency, but has long latencies to open the File Open/Save dialogs, as does any app using the KDE file dialogs.

I also tried this: I logged out both active logins, which took a minute or so (same latency problem), but then I logged the same user into Enlightenment (E17). In E17, I was able to open all these KDE apps without any latency, the problem didn't exist. When I logged out and back into KDE, the problem was also gone, as I've noted previously. I don't understand how this webcam is causing latency in KDE after sleep cycles.

      Code:
dmesg:

Are you using a usb hub, or is the cam plugged directly into the motherboards usb slot ?

It might be some kioslave trying to detect/ connect to your camera and waiting for either results from it or hitting a timeout; is libmtp-runtime installed?

No hub, plugged directly into motherboard USB 2.0 or 3.0 slots and also into additional USB 2.0 slots with USB brackets.

Yes, latest sid version.

In addition to what I wrote above, I wasn't able to reproduce this issue with only one active KDE session today, but as soon as I added a new session with another user, then switched back to my original user, I reproduced the issue after exactly 3 sleep cycles (after the first two cycles, there were no problems). This is consistent with what I've noted previously in this thread.

Once I had reproduced the issue, I also tried adding a third session, logging in my regular user into E17, without logging out the two active KDE sessions, and the there was no latency opening these KDE apps in E17. When I switch back to my KDE session, the latency issue is still there. There is long latency even deleting a file or folder in Dolphin. However, the latency issue doesn't exist in the second active KDE session with another user.
