With nvidia-drivers 334.16 installed on a up2date ~amd64 system, MythTV crashes upon start of mythfrontend, apparently due to libEGL. Downgrading nvidia-drivers fixes the issue. I'm sorry for the sparse information, but I had no time to debug this properly a few days ago since I was hard pressed for time and I have been delaying putting up this bug report until I get the time... which I apparently did not so far. :( Reproducible: Always
Jeroen, I understand it is frustrating if you get such sparse infos and I do apogolize, but please if you need further infos, state what you want and maybe not prematurely close a bug. I have seen at least one other person on the net mention this, so at the very least, if we cannot nail the cause, MythTV should get a blocker or whatever on this particular nvidia blob version as a last resort. Here you go: - making lib64/opengl/nvidia/lib/libGLESv2.so* inaccessible (moving it out or whatever) and mythfrontend starts just fine - limited usefulness backtrace from a crash: #0 0x0000000000000000 in ??

MythTV checks for libGLESv2 at runtime by resolving the OpenGL symbols which it explains why it works by simply moving libGLESv2 out of the way: https://github.com/MythTV/mythtv/blob/master/mythtv/libs/libmythui/mythrender_opengl.cpp#L805 The question is now: Is the segfault caused by a bug in MythTV, an incompatibility between the Mesa and NVidia's implementation or something entirely different. I think re-opening this report would be appropriate as something is indeed fishy and even if it is a bug in the blob, at least a blocker could be put in the mythtv ebuild as a last resort.
Ok, just made a small test case and it is most definitely glGenBuffers crashing. If used w/ the Mesa implementation, it works just fine. But with libGLESv2 from this beta driver, you get a segfault. Seems to be a blob bug then. I'll open a thread on devtalk.
As a reference, here the link to the thread I just opened over at DevTalk: https://devtalk.nvidia.com/default/topic/691399/linux/-334-16-crash-in-libglesv2-with-glgenbuffers-/
You still didn't mention which revision of x11-drivers/nvidia-drivers-334.16 you are using. We're at -r7 now. :)

Issue is also present with current (as of this writing) gentoo amd64 and nvidia-drivers-334.21.
Issue reported to upstream, upstream responded immediately with: https://code.mythtv.org/trac/ticket/12098 patch included in ticket and I can confirm it fixes the issue when using =media-tv/mythtv-0.27_20130924 with =x11-drivers/nvidia-drivers-334.21.

Excellent. I assume they'll put this in the 0.27-fixes branch, which reminds me that I need to issue another version of that. I will look for it and try to issue a version which includes it. Otherwise, user-patches do work with mythtv.
Patch mentioned in #11 is now in master, 0.27/fixes, and now 0.26/fixes (per a late request for our stable branch), so we should be good to go with a new set of ebuilds when you're ready Mr. Freeman.
Ok, 0.27 is updated. I'm going to close this unless cardoe wants to bump 0.26.
