Bug Description

On slow hardware, the breadcrumb bar sometimes show text labels at random size (either really small, or completely hidden, or normal size, or half size).

To reproduce just go in any controller using the breadcrumb, go in some section, then go back, etc.. until you trigger the race.

Obviously this only happen on our slow hardware here.

We've been told this is because the label size is calculated in a racy condition and this is most reproducible on slow hardware.

Can we have a screenshot please?
What do you mean by "go in any controller using the breadcrumb"? Do you navigate using the keyboard/remote, or clicking the actual bread crumbs?

I mean doing this only with a remote :

1) - Go to Music section from carroussel
2) - Go to Library
3) - Go to Folders
4) - Go to Music Folder
5) - Press back until you get back to state 2) and loop until you see the problem.

Attaching screenshot after that comment.

I manage to reproduce the bug (although quite infrequently) by overloading my CPU.

This is very related to Bug 380968 (in my opinion), for which I have a patch, consisting of regenerating the controller widget when it has been mapped.

I've just registered lp:~osomon/elisa/upicek_squashed_breadcrumbs that seems to do the job.
Problem is: it is quite hard for me to reproduce the bug (tried on several configurations, the bug happens very rarely, maybe 1 in 100 or less), and therefore quite hard to validate the fix.

@dolphy: can you please test the branch and let me know the results?

It seems that this patch does the job indeed (confirmed by dolpy over jabber).

I can still reproduce the problem under heavy load (metadata scanner)

Lowering the importance until we get an estimation of the frequency of reproduction of the bug.
