Yes, really strange bug.

I confirm I can reproduce this both in this little script and in a
more complex application of mine which mixes float() calls and pyosd
calls, and the solution is the same in all cases : do the float()
calls BEFORE the pyosd calls

This on both my home computer and my laptop at work

No idea of what the problem could be, time to use a debugger maybe...

Found !!!

the bug is there :

once pyosd is called, you have to do :

        float("55,4")

instead of :

        float("55.4")

for the float() call to work

this has to do with the locale (I'm french, and numbers are separated
with commas here)

not sure where the problem really is though, but this fixes the problem
and may explain why you didn't encounter it

Please tell me how I could be more helpful to solve this problem
definitely

Well spotted. xosd_create contains a call to:

  setlocale (LC_ALL, "");

which will set the program's locale based on the environment. I do not
think a library function should do this. Reassigning to xosd.

Subject: python2.3-osd: python-osd breaks Python builtins functions

Package: python2.3-osd
Version: 0.2.6-1
Severity: critical
Justification: breaks unrelated software

python-osd, when used breaks the float() builtin function

I suppose there's a buffer overflow somewhere which overwrites
some Python buffer or code or something like that

look :

jerome@nordine:~$ python
Python 2.3.4 (#2, Jun 19 2004, 18:15:30)
[GCC 3.3.4 (Debian)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import pyosd
>>> x=pyosd.osd(colour="#FF0000", timeout=5, shadow=2)
>>> y=float('55.4')
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ValueError: invalid literal for float(): 55.4

and without python-osd :

jerome@nordine:~$ python
Python 2.3.4 (#2, Jun 19 2004, 18:15:30)
[GCC 3.3.4 (Debian)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> y=float('55.4')
>>>

no error there.

Interestingly, float('55') seems to work ok even with python-osd

Also interesting is the fact that the float() function works fine BEFORE
the python-osd module's code is used, and breaks after that

Tested on two different machines, with both sarge and unstable
same problem.
