Comment 1 Marco Martin 2017-02-21 12:52:55 UTC 
this backtrace says that a frameData was deleted but not removed correctly from the hash.
I tried to reproduce it by creating and destroying a lot of frames of random sizes, but i don't seem to be able to reproduce it, the framedata that gets deleted seems to be always correctly removed from the hash

Can it possibly be a driver issue?
Comment 3 Marco Martin 2017-02-28 12:35:15 UTC 
Git commit 2b3e8dfe866abc5b2971eecb4c52843e73be1893 by Marco Martin.
Committed on 28/02/2017 at 12:35.
Pushed by mart into branch 'master'.

move setImagePath logic into updateFrameData()

Summary:
make sure the framedata creation/destruction is
completely in updateFrameData, makes easier to track
and possible to use the repaintsblocked logic.
now only one framedata instance should be created at startup.

Test Plan:
* autotests pass, plasma runs ok, crash on 376754 not reproducible anymore
* possible to have a plasmashell session start without the creation of a single svg renderer (startups after the first when the cache is generated)
* on qml profiler, framesvgitem creation is ~12 msecs the first one created, ~2-300 musecs the subsequent ones, seems to be a bit better than before the whole refactor started
* tried against the latest patches that remove the binding loops, still correct rendering and no binding loop
* tried with both empty and existing cache in place
