Hello
I observed that in about 50% of cases freevo crashes directly after
start with the following error message:
INFO __init__(1072): preparing skin settings
INFO __init__(1072): preparing took 0.0331819057465 seconds
ERROR __init__(1072): Crash!
Traceback (most recent call last):

self.channels = kaa.epg.get_channels(sort=True)
File "/usr/lib/python2.4/site-packages/kaa/epg/__init__.py", line 74,
in get_channels
channels = guide.get_channels()[:]
TypeError: unsubscriptable object
In the other cases startup works without problems.
The exeption is occuring in the following code from kaa.epg.__init__.py:
def get_channels(sort=False):
"""
Return a list of all channels.
"""
if not guide.status == DISCONNECTED:
if sort:
channels = guide.get_channels()[:]
channels.sort(lambda a, b: cmp(a.name, b.name))
channels.sort(lambda a, b: cmp_channel(a, b))
return channels
return guide.get_channels()
return []
Everything went fine, if guide.status==DISCONNECTED at this stage of
freevo's booting process, then the call to get_channels returns just a
empty list, which seems to be OK.
If the guide.status is not DISCONNECTED, then the crash occures!
As a fast fix, I changed the code to catch the TypeError exception and
return an empty list instead. But I wonder why freevo is asking for a
channel list so early in its boot process, if it is also quite satisfied
with an empty list here. Another question is, why is the get_channels()
function crashing. It is also called later, when the user opens the
tvguide and then not crashs happen.
I guess there is more behind this...
Regards
Tanja
@Dischi: Sorry, I know you are very busy at the moment, but I send this
nevertheless now, because I do not want to forget it...
