Thanks, this helped.
Now the browsers just dump core on startup:
% epiphany
** (epiphany:11547): WARNING **: Unable to start Zeroconf subsystem
** (epiphany:11547): WARNING **: Throbber animation not found
** (epiphany:11547): WARNING **: Throbber fallback animation not found either
ASSERTION FAILED: isPageAligned(size)
./Source/JavaScriptCore/wtf/PageAllocation.h(101) : static WTF::PageAllocation WTF::PageAllocation::allocate(size_t, WTF::OSAllocator::Usage, bool, bool)
Segmentation fault (core dumped)
% rekonq
unnamed app(11553): Communication problem with "rekonq" , it probably crashed.
Error message was: "org.freedesktop.DBus.Error.NoReply" : " "Message did not receive a reply (timeout by message bus)" "
For epiphany the problem seems to be with webkit-gtk2.
For rekonq is't probably in qt4-webkit.
I'll try to ask upstream.
Thanks again
