Hi all,
Here is my little patch (sorry, a did not use any diff program, as changes
are so small)
in UI/Browser.py (line 125) replace the _resizeColumns method with:

def _resizeColumns(self, index):
  try:
    z = self.__cache_size
  except:
    self.__cache_size = 160 # default width for me

  w = self.sizeHintForColumn(0)
  if w == -1:
    return
  if abs(self.__cache_size-w) > 40: #
    self.header().resizeSection(0, w)
    self.__cache_size = w

Yes, I know, it is ugly, but works for me :)

But the problem seems to be a bit more complicated, as I found that the
ResizeSections(QHeaderView.ResizeToContents) is a fairly large and
time consuming procedure, at least in Qt4.3.1, see below

I did some time comparisons when using different libraries / distros on same
machine
AMD Sempron 3400+ 1.8GHz

the result (browsing middle size project - about 20 subfolders):
- When using Zenwalk -march=i486 -mtune=i686, QT4.3.1 PyQt4 - latest-devel,
QScintilla2 - latest-devel, eric4 - latest-devel, sip - latest-devel
expanding a branch - up to 1.5s

- when using the same library as abowe, but eric4 has been patched
expanding a branch - no more 1s, actualy varying from 0.2 to 0.8s

- When using Linuxmint (Ubuntu Feisty)  QT4 2.3, PyQt4.1, QScintilla2 -
latest-devel, eric4 - latest-devel, no patch for eric
expanding a branch - no more 0.3sec and I'm hapy

So, it seems there is something wrong in QT4 library itself.
I'm still working to find out the differences between two ones;
