hgview crashes if repository is empty

[grofaty]

Binary package hint: hgview

1. On Ubuntu 10.10 I have installed Mercurial and hgview:
sudo apt-get install mercurial
sudo apt-get install hgview

2. Then I have created repository:
hg init main
Note: main is the name of newly created repository.

3. Change directory to newly created directory.
cd main

4. Run hgview
hgview

Program crashed with the following error message in terminal:
===========
Traceback (most recent call last):
  File "/usr/lib/pymodules/python2.6/hgviewlib/qt4/hgrepoview.py", line 168, in resizeEvent
    self.resizeColumns()

    w = model.maxWidthValueForColumn(c)

===========

It looks like if repository does not have at least one file and hgview is run, then hgview crashes.
Crash of the program should never happen. It would be nice if hgview would just start with empty windows.
