IOError 4 with pipes

[Giuseppe Corbelli]

Hi
I've done a pygtk GUI to cmdline program (global source indexing) as a
plugin for glimmer text editor.
It uses os.popen to exec the prog and read the output.
I developed it with Python 2.1 without problems.
Updated Linux distro do Mdk 8.2 and began getting
Traceback (most recent call last):
  File "/usr/lib/python2.2/site-packages/libglade.py", line 28, in __call__
    ret = apply(self.func, a)
  File "/usr/local/share/glimmer/scripts/Global.py", line 510, in
__on_searchbutton_cb
    completionlist = self.search (tag, self.__searchtype)
  File "/usr/local/share/glimmer/scripts/Global.py", line 162, in search
    for line in xreadlines.xreadlines (pipe):
IOError: [Errno 4] Interrupted system call

Offending line is

pipe = os.popen (self.__global_path+" -ax '"+initial_string+"'", 'r')

Of course exe path is correct.

Tried other pipe methods (popen2,3,popen3 class) without luck, keep getting
same error.
I am unable to understand why.
