Hm, strange, the regex does match:

root at blue:/mnt/user/tm-mark/Yavin4.sparsebundle# grep -A1 "^[[:blank:]]*<key>band-size</key>$" Info.plist 
	<key>band-size</key>
	<integer>204800000</integer>

I notice the timestamp of the Info.plist is from today :

root at alderaan:/mnt/user/tm-mark/Yavin4.sparsebundle# ls -al Info*
-rwxrw-rw- 1 markr users 575 Nov 19 07:02 Info.bckup*
-rwxrw-rw- 1 markr users 575 Nov 19 07:02 Info.plist*

Perhaps this file gets rewritten at the same time as fruit_get_bandsize() checks it. Like some rat race condition? That would explain I only a few times a day (Time Machine backups run each hour).

Could this be related:
