hi, Hiro, sorry for some cluelessness on my part (i'm really an ex-BSD guy, so part of my problem is not having any clue about linux; also, i'm a gray-haired guy, so even multi-threading is sort of "after my time").
if you've patience, a few follow up questions: > reinstall your system (yes, everything) is this a reinstall from source, or from my original (lubuntu) distribution? (but, see the last point below.) > and disable all this bullshit crap like dbus, i guess the answer to "how" here depends on whether i'm installing from source. but, a pointer to "how" would be appreciated. (it's all in the learning.) > keep the debug symbols enabled it would be great to have all debug symbols, for all installed libraries, plus the kernel. again, the 'how' -- other than installing "-dbg" every time -- to do this... > and make sure gdb follows the right thread that actually > segfaults. hmm, seems like a postgraduate thing -- maybe i'll leave this till the time i've fulfilled the (above) requirements? > if you can't do that and want to keep on using a horrible linux > distribution that enables all kinds of useless features like dbus by > default, then use a browser that is supported by your distribution. so, i'm running lubuntu because it seemed to me the most "mainstream" + "stripped down" distribution i'd run into. i'm running an Entroware "Apollo" laptop, so need things like wifi, suspend/resume. if you've a suggestion for an alternate distribution (or two, or three), i'd love to hear. cheers, Greg
