[Ktechlab-devel] Re: Creating new component - Decoder

[Fredy Yanardi]

Hi,

I'm sorry for the 2 source codes I sent yesterday, they contain
errors, because yesterday I use multiplexer component to create these
decoder components. Today I've fixed it, but I still can't fix error
when deleting the object.

Backtrace from the KDE Crash handler gives me this:

Using host libthread_db library "/lib/tls/libthread_db.so.1".
`system-supplied DSO at 0xffffe000' has disappeared; keeping its symbols.

Sorry if you think some of my questions are dumb, but I'm newbie in
KDE programming and in large project like this.
