Xpra: Ticket #1374: Printing doesn't work anymore with XPRA_HTML5

Testing build xpra-1.0-1.r14502.el7_2.x86_64.

Printing is not working anymore with XPRA_HTML5. Please find XPRA_SERVER logs attached.

I made test with exact platform, but connected with XPRA_CLIENT and it works.

Thanks and regards,

Are you sure that this is a regression?

I am not seeing any differences between 0.17.x and 1.0.x

Are you sure that your browser isn't just blocking the popup which we use for printing? ie: Turn pop-ups on or off

For sure this is not a popup issue as I use regularly r14232 and popups come.

It could be the browser caching html pages from this release, not compatible with last server build ?

I'll give it a try, with browser cache cleaned.

Thanks and regards,

I made a test, and here is an error from the Firefox (50.0.2) webconsole:

Silly me, sorry about that, r14500 had fixed this bug just before 1.0, but that was already after 1.0 got tagged so it didn't get included in the release... r14532 applies it to the v1.0.x branch.

Either apply it by hand or wait for 1.0.1

Not heard back, I assume this was fixed, feel free to re-open if not.
