[Hussam Al-Tayeb]

Same issue in 2.15.4
In addition, yelp shows a page saying:
"Unknown Error
Load request cancelled"
when it breaks.

[Carlos Garcia Campos]

I could reproduce this for a while, but not anymore :-(

Did you perhaps update to a post 2.15.4 snapshot and it started working again?

Using current trunk all the time

[Jeremy Bicha]

I can duplicate this bug pretty easily with webkit2gtk 2.15.4-1ubuntu2 (that adds the CodeBlocks.h patch from 167785 and the yelp video patch from https://bugs.webkit.org/show_bug.cgi?id=167309 ) on Ubuntu GNOME 17.04 Alpha.

To duplicate, click several different links in the Getting Started section of the default GNOME 3.22 help (which has embedded videos). I wasn't able to duplicate by repeatedly clicking links in the other parts of the default GNOME help.

[Michael Catanzaro]

I tried to reproduce this today but failed. Carlos, I agree your recent custom protocol fixes are likely suspects. Hussam, Jeremy, we're going to release 2.15.90 later this week; please check it to see if you can reproduce there.

[Michael Catanzaro]

Hussam says this is fixed in 2.15.90, so I'll close this now. Please reopen if you can reproduce with 2.15.90.

[Jeremy Bicha]

Yes, 2.15.90 is working a lot better here. Thanks!
