Is the message "QLock::lock(): Identifier removed" anything I should be concerned about?

[kottkungen]

I have a platform with an optional secondary display. Since I want to separate the two displays I've split the code into two applications, one for the primary display and one for the secondary. I start them by running
@
./app_1 -qws -display linuxfb:/dev/fb0 &
if [ -e /dev/fb1 ]
then
./app_2 -qws -display linuxfb:/dev/fb1 &
fi
@

But now I started to see the output:
@
QLock::lock(): Identifier removed
QLock::unlock(): Unlock without corresponding lock
QLock::lock(): Identifier removed
QLock::unlock(): Unlock without corresponding lock
QLock::lock(): Identifier removed
QLock::unlock(): Unlock without corresponding lock
@

Is this something I should be concerned about? Is this caused by running several qws:es? Or should I look for the error somewhere else?

Thanks

It does seem to be a problem, after a while one of the screen freezes. My guess is that the process deadlocks. It's been a while since I compiled Qt, and I don't have the config files. But from what I can see in my qconfig.pri it seems like most of the things are enabled. Does anyone have any advice on what to look for?

Hello kottkungen, I know this is an old post
but did you solve this? I have exactly same configuration with two QWS applications
on different fbs and exactly same error messages.

Thank you for your help
