StartupMacros not loading on Linux system

I have a strange behaviour on Linux

If I execute imageJ from its normal working path, the startupMacros are not
loaded (my own compile). If I run the same imageJ from within JBuilder2006,
then the startup macros are loaded as expected. The macros also load
perfectly normal with the SAME compiled imageJ if I run it on a Windows PC.

Given that the problem does not occur from within JBuilder, this is a bit
tricky to debug, however, I dug down with a lot of System.out.println
commands to narrow the problem down.

in Menus.java, version 1.41h line 782 macrosPath is defined correctly:
  macrosPath = pluginsDir+Prefs.separator+"macros"+Prefs.separator;

//but then
  macrosPath = pluginsDir+Prefs.separator+"macros"+Prefs.separator;
}
File f = macrosPath!=null?new File(macrosPath):null;
  if (f!=null && !f.isDirectory())
    macrosPath = null;

macrosPath is set to null on Linux if and only if run from a console due to
f.isDirectory()
returning an incorrect value.

I ruled out that this is a file permission problem by double-checking
permissions and repeating the test as a superuser. I am appending some log
messages I got from additional System.out.println statements when running
ImageJ as either from a superuser shell (macros failing to load) or from
within JBuilder (working as expected and as on a Windows system).

System:
imageJ version 1.39s (but should also happen in 1.41h from a quick look at
the code)
SUSE 10.3 x64, jdk1.6.0_04, JBuilder2006, reproducible on SUSE 11 x64 with
jdk1.6.0_08

Any ideas or workarounds most welcome!
