Please don't paste log data into the ticket description, use some WikiFormatting instead. Also fill in some descriptive info as in ​the guide.

See ​this thread, possibly related to ​this ticket that has already been patched, but after 2.4.8 was out.

Matainers: is there a reason this port is 2.4.8 while there are versions 2.6 and 2.8 released?

[dbevans (David B. Evans)]

Duplicate of #47430 which discusses the issue and has a tentative fix. Please check for existing tickets before submitting a new one.

Concerning later versions: versions 2.6+ abruptly switched to a cmake build system as well as significant refactoring of the code. webkit-gtk 1.0 API is dropped entirely and there are ongoing issues with getting webkit2-gtk to build. Both Jeremy and I have been working on this but no luck as yet and not much help from upstream. It is continues to be a high priority with me.

When this was opened the summary of #47430 was different so it wouldn't come out while looking for webkit-gtk3.

Replying to and.damore@…:

When this was opened the summary of #47430 was different so it wouldn't come out while looking for webkit-gtk3.

True, that's why I changed the summary of the ticket to more closely reflect the true nature of the problem. However it is the same problem and a slightly less restrictive search on webkit-gtk would have revealed the previous tickets.

At any rate, sorry for being grumpy about it.
