Eliah, thanks for the analysis you've done, that's quite helpful. You mention that the bug you encountered is "almost certainly" a dupe of this one, however looking at both bug 876799 and bug 887189, I'm not immediately spotting clear evidence that it is indeed a dupe. Would you mind elaborating on how you're determining it?
>From the stacktraces on your bug reports, it looks like the only thing in common is the _kernel_vsyscall line, but that could mean anything. What really must match in your backtrace for it to be a dupe is this bit: #3 0x05cf3718 in *__GI___assert_fail (assertion=0x16927e5 "ret != inval_id", file=0x16927a9 "../../src/xcb_io.c", line=385, function=0x1692964 "_XAllocID") at assert.c:81 buf = 0x960c538 "synaptic: ../../src/xcb_io.c:385: _XAllocID: Assertion `ret != inval_id' failed.\n" I suspect the "Assertion `ret != inval_id' failed." error message should show up in one of your logs (probably .xsession-errors, but also check /var/log/lightdm/* and /var/log/Xorg.0.log). I'm going to drop the 'precise' tag until there is stronger verification that the bug does exist. ** Tags removed: precise -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to libx11 in Ubuntu. https://bugs.launchpad.net/bugs/507062 Title: synaptic assert failure: synaptic: ../../src/xcb_io.c:385: _XAllocID: Assertion `ret != inval_id' failed.
