Logitech QuickCam service blocks Firefox build...

Although it's a known issue in bugzilla I was still really surprised. After reading the log I can see the "rebase" dll caused the problem.

Why does make often crash creating a sh.exe.stackdump file when I try to
compile my source code?
If you experience random crashes with make as well as with the msysinfo command

Nonetheless, the camera will keep working just ok with 3rd party software

process whenever you want to use MSYS by typing at the command prompt: pskill
-t lvprcsrv.exe (you will need PsTools and administrator privileges to do
this). However, as soon as you will plug in the USB cable of your Logitech
QuickCam, the daemon will be restarted, while with the first procedure it
