Keep KService::createInstance error message in KServiceTypeTrader::createInstanceFromQuery
Review Request #107032 - Created Oct. 25, 2012 and submitted
When KServiceTypeTrader::createInstanceFromQuery fails in KService::createInstance, the error message is currently overwritten by the useless information "No service matching the requirements was found". This patch fixes that to keep the error message set by KService::createInstance and thus give me something more useful like e.g. "Cannot load library /home/milian/projects/compiled/kde4/lib/kde4/kdevqmljslanguagesupport.so: (libqtc-qmlsupport.so: cannot open shared object file: No such file or directory)" '
changed the header, ran KDevelop with invalid plugins, got actually useful output (see above). Another example that was overwritten as well before this patch: "Cannot load library /home/milian/projects/compiled/kde4/lib/kde4/kdevfiletemplates.so: (/home/milian/projects/compiled/kde4/lib/kde4/kdevfiletemplates.so: undefined symbol: _ZTIN8KDevelop17ITemplateProviderE)" '
OK. In case of multiple offers with error, this will return the error from the loading of the last one, but I guess that's OK (no room for all, and the problem is probably the same on all of them anyway, e.g. undef symbol in Qt or another shared lib).
