<p class=MsoNormal><font size=2 face=Tahoma><span style='font-size:10.0pt;
font-family:Tahoma'>I have an application that works 90% of the time. It is
rock-solid on desktops, but the 10% is laptop installed base. The laptops
seem to have two issues:<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Tahoma><span style='font-size:10.0pt;
font-family:Tahoma'>On 1 computer in particular, python.exe crashes whenever
you open a document outside of the application, such as an Excel file, but it
does nto crash when a browser is opening cache files. Right after the double
click but before excel has actually opened, the application crash dialog comes
up. This violates the notion of private address space and process separation. (This
is on XP.)<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Tahoma><span style='font-size:10.0pt;
font-family:Tahoma'>The other crazy problem is with QHttp, as far as I can tell.
We have a function that does a simple get() to obtain the latest version number
of the software (to see if an update is available) in the “background”.
This request is performed, but it seems when the response is received it crashes
the program. Weirder yet, the affected laptops seem to have Verizon wireless
cards, but not in every case, just most of them. It does not seem to matter if
they are using VZW or a CAT5 cable.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Tahoma><span style='font-size:10.0pt;
font-family:Tahoma'>I can’t imagine what could be causing these issues, I
am hoping someone out there could see a potential conflict, or some GIL knowledge
that I am lacking, or if there is some debugging technique that I can use. AFAIK,
all this is happening in one thread. The illusion is multitasking is created by
signals/slots. The crashes were reported in the original version using 4.2.3,
and are still present in 4.3.1.<o:p></o:p></span></font></p>
