Hello everybody,
We are repeatedly running into an assert while clicking in a web page shown
using QtWebKit, we currently using Qt 4.8.5. After changing the ASSERT macro to
not call the CRASH macro to prevent our application from crashing while in
debug mode there don't appear to be any issues but is it safe to ignore this
assert?
Assert on double click:
ASSERT(prev != *this);
