I think Ehsan's pretty right.

So, options are 3 now:
*1 Don't modify the Mozilla Thunderbird's settings into code for the 
"CONDSTORE" stuff — Release next Thunderbird major branch with no 
modification at all.
*2 Disable "CONDSTORE" thing only in Gmail IMAP service & release 
Thunderbird 24 with this modification implemented. Thing is… do we know 
any metrics about people out there using labels in Thunderbird? They 
must be the less, for sure. But I'm one of those weird animals who use 
labels & filters madly. :( What percentage of Tb users will be affected?
*3 Get in touch with Google folks. Why they would modify the "CONDSTORE" 
setting when most people access Gmail from the webmail interface? 
Besides, having Gmail the access for POP3 & IMAP, they should have had 
contacted email clients developers by themselves —like Mozilla— to tell 
what's news, shouldn't they?

Whatever. IMHO, a 2 weeks period isn't quite enough to test this. And 
I'm afraid Google isn't rollin' a workaround on within next weeks either.
All best,
