[Lazarus] Default ico handling and recent debugger errors

[JuuS]

While testing RC1 and 2 I followed the suggestion to open a published
project and see how the release candidates were doing with them.

Upon doing this I got an immediate debugger error, which has been traced
down now (as of last night) with the help of Martin and is fixed.

The problems origins were (and still are to some extent)...weird.

Before a debugger solution was found I could stop the error by simply
removing the "default icon" line from the published project's LPI file,
then no debugger error.

During all the research I could see that while the LPI file had a
"default icon" line, the publishing process did not copy the ico file to
the published diretory.

So there was always a background silent error due to the fact that the
icon file didn't exist, the silent exception (seen when debugging
Lazarus) was on trying to open this nonexisting file.

How this all caused the debugger error is, as I have said, still not
entirely understood.

So it just brings to my mind that even though this error has no effect
in most cases it may be best to either copy the ico file on publishing
the project, or not writing a "default icon" line in LPI, or checking
that the ico file actually does exist and recreating it if not; just in
case it has other effects that will cause other "weird" errors down the
line.
