Hi Renato Araujo Oliveira Filho,
Looks like I just experienced the same problem. Please look at attached
source. It fails with the latest PySide from git on Linux x64 and on
Windows with Python 2.6.6 and the latest beta5 package from
http://pypi.python.org/packages/2.6/P/PySide/PySide-1.0.0beta5qt471.win32-py2.6.exe
If I create more than 13 signals, some of emitters do nothing. Should i
fill a bug report?
Thanks in advance,
Vladimir
Could you create a small example with this problem. With this I can
check exactly what is happening and check if this is a bug on PySide.
