0.8.6 -> 0.8.8 go boom

DiapDealer · 07-06-2011, 08:58 AM

Windows Vista (32-bit)

After the upgrade I get the splash screen and then... nothing. Calibre.exe shows in the process list, but just sits there. I let it sit there for a very long time then killed the process.

calibre-debug -g output:

Code:

Starting up...
Traceback (most recent call last):
  File "site-packages\calibre\gui2\main.py", line 260, in initialize
  File "site-packages\calibre\gui2\main.py", line 241, in initialize_db

  File "site-packages\calibre\gui2\library\views.py", line 54, in __init__
KeyError: 'horizontal_scrolling_per_column'

Any suggestions?

Your mixing a default_tweaks.py file from two different versions of calibre. Search your computer for this file and ensure the only one present is in the calibre installation folder.

Interesting. I always leave the CALIBRE_DEVELOP_FROM environment variable set up, but I point it to a non-existent dummy folder ".../calibre/srcjunk" instead of ".../calibre/src" within my calibre source repo... basically because I'm lazy and don't want to setup the environment variable from scratch each and every time.

To make a long story short... it was using the defaults_tweaks.py file from the ".../calibre" folder of my source repo. Deleting the environment variable fixed it. I didn't realize any of the parent directories of the CALIBRE_DEVELOP_FROM env var were in play. I wasn't running from src or anything... the asterisk wasn't showing up in the GUI before I upgraded, anyway. Oh well.

Anyway, thanks for pointing me in the right direction.
