The loading code (for bundles which are active in your preferences and 
get loaded at startup) is in:
TalkSoupBundles/TalkSoup.m

in method:
static inline id activate_bundle(NSDictionary *a, NSString *name)

at the end the code is very simple:

bundle = [NSBundle bundleWithPath: dir];
return [[[[bundle principalClass] alloc] init] autorelease];

I see that "dir" is correct, but then bundle is wrong. Not for all 
bundles, but for some. Empyrically I found that e.g. the bundle loaded 
*after* dccsupport is wrong.

The plist content might be the problem, it looks, once installed like this:

{
    CFBundleDevelopmentRegion = English;
    CFBundleExecutable = "${EXECUTABLE_NAME}";
    CFBundleIdentifier = "org.gnustep.${PRODUCT_NAME:rfc1034identifier}";
    CFBundleInfoDictionaryVersion = "6.0";
    CFBundlePackageType = BNDL;
    CFBundleShortVersionString = "1.0";
    CFBundleSignature = "????";
    CFBundleVersion = 1;
    NOTE = "Automatically generated, do not edit!";
    NSExecutable = MessageInTab;
    NSMainNibFile = "";
    NSPrincipalClass = MessageInTab;
}

all the CFBundle* stuff is "new", it appears to be merged in from the 
Cocoa plist. The CFBundleIdentifier is always the same.
In fact, that is the problem: if I remove from the plist that line, the 
next loaded bundle will be the problem.
So apparently we respect that identifier if present but it can be omitted.

Each bundle has a Ignore-Info.plist in its directory which is XCode 
information, why do we "merge" it in? I want it to be ignored, XCode 
does some substitution in it before putting it in the bundle.

How does actually gnustep-make guess stuff like NSPrincipalClass?

It is thus somehow a build problem: GNUstep make tries to be smart, 
merges in some Mac stuff which confuses then the code at runtime.
