Because they're very different technologies with very different kinds of bugs? There's a reason the fallback is there already. and that's just the unintended ways it can fail, then you have users that for some reasons intentionally don't run plasma-shell with the default settings, use another tray solution, etc. > 2) why the other patch doesn't work. The other patch won't work because it doesn't know if the plasma integration plugin is loaded. it's also the wrong place to put those kinds of checks, even if you would find a 100% bulletproof bug free way to detect that. hardcoding in fixes for bugs in platform plugins (e. g. if another platform plugin decides to do the same) is wrong. and as already demonstrated, it doesn't work well in practice. > 1) why this is needed to avoid applications hanging/crashing, approach the zen of failing gracefully, and in general make this a bit more robust. imho, this shouldn't even be using the same KSNI classes that applications are supposed to use, it's a design error that leads to these kinds of problems, but this makes it a bit more sane. but this discussion was absurd several posts ago, and it's not getting better... - Martin Tobias Holmedahl ----------------------------------------------------------- This is an automatically generated e-mail.
