No.
Bugfixes don't go in a patch release unless they meet some criteria.
The reason is that we must do our best effort not to make a patch release 
worse than the previous version.  
The worse things that can happen to an application developer is a regression: 
something that was working before and is no longer working.  Any kind of 
behaviour change might be a regression for someone.
Any patch may have unknown unwanted side effect.
For this reason we limit the bugs that are fixed in patch release to critical 
bugs (such as crashes or security issues) and regressions from past releases.

In this case, this is not a regression.  The bug always was there and user 
lived with it, it is therefore not critical.
Also, it is clearly a behaviour change: an application developer might have 
relied on the fact that we fallback on the fallback theme first or on the 
fallback icon.

The criteria are documented there:
http://qt-project.org/wiki/Branch-Guidelines#8321dab5f8fcb86ed31375494ce0a743

Remember that "stable" means something that is not changing, not something 
that has no bugs.
