Oh, yea, forgot the assert reason: konqueror: /home/thiago/programs/src/kde/kdelibs/khtml/misc/loader.cpp:1434: static khtml::CachedCSSStyleSheet* khtml::Cache::requestStyleSheet(khtml::DocLoader*, const DOM::DOMString&, bool, long int, const QString&, const char*): Assertiva `o->type() == CachedObject::CSSStyleSheet' falhou.
This wasn't an easy bug to trace down, but I finally came up with a simple test case. It's online at http://luispedro.org/~luis/bugs-kde/68181/test1.html The main part is: file1 : <img src="style.css" /> for preloading file2 : <link res="stylesheet" href="style.css" /> CRASH: style.css is preloaded as image !!! <not-interesting except-for="programmers"> What took me a long time was that I was trying to follow the object creation/insertion but due to the use of multiple inheritance, two different pointers can refer to the same object and so the logs were apparently impossible: the cache returned an object which had never been inserted! The real problem was that I was using: kdDebug() << "Inserting: " << p << endl; cache->insert(p,_); instead of kdDebug() << "Inserting: " << (CachedObject*)p << endl; cache->insert(p,_); Since p was a CachedImage which inhearits from QObject and CachedObject, the pointers were not the same </not-interesting> Probably the solution is something like: - assert ( o->type == CSS ); + if ( o->type != CSS ) { + delete o; + removeFromCache(o); + fetch(o), + } I will try to prepare a patch (but today I must go and do some for-school work, so maybe tomorrow - but I don't really know the internals here). hth, luis
