[timeless]

so, afaik vlc has reached 1.0.5, and we've asked our plugin team to blocklist 0.9.6 and earlier. i have zero sympathy for your crashy plugin.

could you please try updating to 1.0.5?

Comment 2

[[:Aleksej]]

No, I cannot update to 1.0.5 (and I don't use plug-ins).

Comment 3

[Frank Wein [:mcsmurf]]

You cannot update?! Why that? If your distribution only offers very old software, we cannot help you with that..

I see the same kind of error with VLC 1.0.2

nsPluginNativeWindowGtk2: NPPVpluginNeedsXEmbed=0
About to create new xtbin of 624 X 370 from 0x4a007ac...
About to show xtbin(0x7f6530925e00)...
completed gtk_widget_show(0x7f6530925e00)
nsPluginNativeWindowGtk2: call SetWindow with xid=0x5a00001
Error: Couldn't find per display information

It's trying to use an Xtbin container (which we haven't really tested yet), and something's going wrong along the way.

This will be fixed by either the Xt bin impl or a plugin whitelist.

This looks similar to the error in linux bug 547153:
###!!! [Parent][RPCChannel] Error: Channel error: cannot send/recv"

Comment 7

[Benjamin Smedberg]

What is the plugin file name for the VLC plugin?

Looks like 'i686' is old Athlon/Duron based architecture.. and

'CPU has capabilities 486 586 MMX 3DNow! MMXEXT SSE FPU'

and just based on this bug alone, 1.0.5 sounds like its probably not compatible with your combination.

There are valid reasons people have to use older hardware at times and hense stuck with older software too.

I hope this puts an end to this discussion:
This computer has 256 MiB of RAM, so I'm staying mostly with Debian stable. The newer VLC package depends on a newer libc (though that doesn't require updating everything else). I haven't really used plug-ins for years, so I don't care enough to look for a compatible package or to try compiling one.

Thanks, Benjamin.  I probably would have put this in #ifdef MOZ_X11, but that's not essential.

Thank you, Aleksej for the bug report.

Verified fixed with Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.3a2pre) Gecko/20100226 Minefield/3.7a2pre

Works with dom.ipc.plugins.enabled.libvlcplugin.so set to "false", crashes with it set to "true".

No problem.
