> Local event loop in QApt::CacheBuildProgress::Update() ?

I don't have much experience, is it fixable?
Comment 3 Aleix Pol 2014-01-14 00:38:26 UTC 
Cristoph, what do you mean by local event loop?

Comment 5 Harald Sitter 2014-03-21 10:32:11 UTC 
Qapt internally triggers event loop processing while waiting for stuff to prevent GUI lockups. In turn however this leads to the user being able to crash any qapt application by clicking on stuff while (for example) the cache is being rebuilt internally.

This was however removed, so 2.1.70 probably doesn't show this anymore.
