calibre package has bad softlink / IOError: cannot open resource

[Chris Bainbridge]

calibre looks in wrong directory for font

$ ebook-convert x.recipe x.txt

Traceback (most recent call last):
  File "/usr/lib/calibre/calibre/web/feeds/news.py", line 1033, in build_index
    self.default_masthead_image(self.masthead_path)
  File "/usr/lib/calibre/calibre/web/feeds/news.py", line 1216, in default_masthead_image
    width=self.MI_WIDTH, height=self.MI_HEIGHT)
  File "/usr/lib/calibre/calibre/ebooks/__init__.py", line 244, in generate_masthead
    font = ImageFont.truetype(default_font, 48, encoding='unic')
  File "/home/chrb/bin/pil-116/lib/python2.5/site-packages/PIL/ImageFont.py", line 205, in truetype
    return FreeTypeFont(filename, size, index, encoding)
  File "/home/chrb/bin/pil-116/lib/python2.5/site-packages/PIL/ImageFont.py", line 121, in __init__
    self.font = _imagingft.getfont(file, size, index, encoding)
IOError: cannot open resource

# Calibre is trying to load /usr/share/calibre/fonts/liberation/LiberationSerif-Bold.ttf because in ebooks/__init__.py we have
# font_path = default_font = P('fonts/liberation/LiberationSerif-Bold.ttf')

$ ls -l /usr/share/fonts/truetype/liberation/LiberationSerif-Bold.ttf
-rw-r--r-- 1 root root 144K Jul 12 22:12 /usr/share/fonts/truetype/liberation/LiberationSerif-Bold.ttf

$ ls -l /usr/share/calibre/fonts/liberation
lrwxrwxrwx 1 root root 35 Feb 10 2012 /usr/share/calibre/fonts/liberation -> ../../fonts/truetype/ttf-liberation

$ ls -H /usr/share/calibre/fonts/liberation
ls: cannot access /usr/share/calibre/fonts/liberation: No such file or directory

So calibre includes a softlink that points to nothing; "ttf-liberation" should be just "liberation".

Status changed to 'Confirmed' because the bug affects multiple users.

Looks like Debian had the same issue: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=674838

This also breaks the new fetch feature for me and I suspect has been the cause of some of the other reported bugs and crashes.

After manually correcting the symlink /usr/share/calibre/fonts/liberation to point to ../../fonts/truetype/liberation/ calibre is working again for me.

This is fixed as described. Verified on trusty. Thank you for reporting.
