    Hi there,

    I have a problem and I'm bringing it to the programming forum since it's about crash reports and I thought you guys are probably the ones most able to help. I'm not a dev, so I don't know what to make of iPhone crash reports.

    So here it goes... I'm using an iPhone 4 on iOS 5.0, jailbroken with redsn0w. Saturday night the music player started crashing immediately when I tried to launch it. I tried respringing, rebooting... nothing worked. Then, while looking around I saw that the Settings app would also crash on the Usage page, when attempting to calculate/display storage space used by each app. So I thought there had to be some bad file. I went into iFile and deleted the only new audio file I had downloaded during the last 1-2 days (was a podcast), but that also didn't help. Maybe I should mention that I can start playing music from the switcher (and it shows as playing through the Music app) and the controls in the the switcher all work. Same goes for doube pressing the home button on lockscreen - everything works
    and artwork is displayed.
    Also I haven't installed any new JB tweaks or apps before this started to happen. Just updated Foursquare and Google Translate apps (which I even tried to uninstall, although logically there shouldn't be any connection).

    I'll attach the crash reports for both Music and Settings apps, in the hopes that someone here has some sugestion/fix. Oh just one thing - before you suggest to restore my phone, I know that would be the (really) easy way out, but I'm hoping for another solution, since i don't wanna go to iOS 5.0.1

    Many thanks to anyone who might take the time to look into this.

    If you could paste the error log directly in your post I'd be appreciated... Those of us using Safari on non-jail broken iOS devices can't download .txt files.

    I'll take a look when I have a chance on my computer, but I would guess you'd be better off contacting the developer of the app... I don't think the people on these forums have much experience with jail broken devices (Apple has kicked people from the official app store for having relations with the jailbreak community)

    Edit: Alright, I'm not exactly a pro with these things, but I believe the important part is this:

    The application is the default iOS music player, so it's a bit hard to contact the developer :) And i mentioned being jailbroken just to be thorough in my problem description, but this happened right after i downloaded a podcast from the official iTunes store. So... i don't think the jailbreak should be causing this. If anything it might help (accessing the filesystem, editing files). But I might be wrong, of course, this is just the way I see it :)

    Thanks for taking interest in my problem, but I can't give you the crash reports as text in the post, because even just one of them goes over the 20,000 character limit :(

    I wasn't aware there was a post length limit... Maybe I just don't have one because I've been a member for four years?

    In any event, I edited my previous post to have what I think is the important info from the crash logs... I don't really know what to do with the info, though. If I was the developer I could take the log and find the issue in my code, but since Apple is the developer, I'm not really sure what you can do...
