I tried to reproduce this in a valgrind session but have to confess I do not
know where to insert these settings. Choosing "Data sources" -> "New" in the
config dialog I cannot insert these settings. I selected "Library of Congress"
and inserted the server and port number but failed to specify a database,
character set and other settings.

You don't want to use a preset server, so uncheck that box. Then all the 
others get enabled. The search terms get entered in the Internet Search 
dialog after selecting the source.

That's weird. Valgrind was showing a call for a negative column number? 
Maybe Qt uses -1 as some sort of error checking for a column number? That's 
a head-scratcher...

Will try it.

Yes, -1 was used, which resulted in accessing an array at index -1.
This was during the start up phase at which no column was selected at
all.
Please note that this is not related to the crash I reported.

Thanks, now I really understand! But I do not have a z39.50 source in
this dialog that's why I was so confused :-)

I use the subversion code from branch tellico-1.2.x and didn't forgot to
call "make install". Not sure whether z39.50 support is just a piece of
C++ source code (probably) or an external (XML?) file/plugin.

OK, I can search for it ...

Thanks,
Jens

You need libyaz installed for the z3950 source to show up.

The other thing that makes this tricky is the z3950 connection is the only 
part of Tellico that runs in a separate thread. So there may well be 
multi-threading issues that are popping up and causing mischief.

OK, the "Merge Collection" option on import now does just that, a little 
better. New fields values are added, and paragraph fields are concatenated.

I just checked in a change so that the space is no longer required. That 
should make it a bit more lenient.

That should be fixed now, too. 

I'll probably have a 1.2.10 released this weekend sometime.

[Wish] Clickable URL in Paragraph

Hi

Actualy, tellico offers a field for simple text, which is handled as 
an url. You can click then beneath the field, and open the url in the
standard-browser. Thats ok, so far. But it has an disadvantage: it can 
only store one url. So, for some of my collections, i wished for a more 
dynamic solution, which allow me to save as many urls as needed. While it 
would be mainly stupid, IMHO, to add an extra-field for any extra-url, i 
came accros the idea, to use the paragraph-field.

So, my wish is, that the paragraph-field can transform text-urls to
clickable urls. Or that there will be an new multiline-field, which 
handles any seperate line, as an clickable url.

thanks in advance

Daniel
