[Sparkle] Crashes of recent Sparkle svn on 10.3.x

[Julian Mayer]

hello all
two weeks ago i released updated versions of my projects with Sparkle  
revision r117 (instead of the 1.1 release) because i had been getting  
occasional crashreports that seemed to stem from Sparkle, and 1.1 is  
quite old and seemed deprecated anyway.

since then i've received nearly 300 crashreports from users on 10.3.9  
which all showed the same crash in isRunningFromDiskImage ->  
propertiesForPath -> dictionaryWithObjectsAndKeys

here is the backtrace: http://pastebin.ca/910292

in the hopes of fixing these crashes i released other updates a few  
hours ago, including Sparkle r128 which i have modified to omit the  
isRunningFromDiskImage-check to fix the crash.

however once again crashreports from the 10.3.9 users are coming in  
masses this time crashing in
"[RSS initWithURL:normalize:userAgent:]"

here is the backtrace: http://pastebin.ca/910295


so, is there any recent version of Sparkle that also works on 10.3.9  
or do i have to revert back to 1.1 which also has its share of  crash  
bugs?

thanks, julian
