Thanks for the bug report, but to be honest, I'm not sure how much we can actually do about Mac-only bugs, considering that to my knowledge, noone working on Dolphin owns a Mac. Moreover, the backtrace looks like it might actually be a kdelibs issue.

Could you at least install debugging symbols to give us a chance to understand what's going wrong? Thanks.

I will try. Not sure that macports provide debug symbols like package, as all is compiled as well.

Or perhaps it's a specific option to pass when package are installed to compile source code with debug symbol.

Another details : Dolphin crash in all condition when i change current dir opened, not only when i go to root dir from left sidebar. For ex, when i want to go to a subdir listed in central list view, i take the same crash...

Any further information about this? Considering that there seems to be an infinite recursion, it would help to at least know which parts of the backtrace are repeated over and over again in the frames that are left out.

I tried to get a better backtrace to recompile Doplhin through macports, using +debug argument passed on whole KDE packages. No Chance, the trace still always the same. There is no more debug information. Perhaps the problem is outside KDELibs core or Dolphin, as kioslaves or DBus for ex ?

Hm, is gdb on Mac really not able to tell you anything about the frames between #12 and #16893?

No, it's always the same :

Git commit 04229f8f6c3b5c7732251ea4dd038b5fc81fc388 by Frank Reininghaus.
Committed on 23/06/2013 at 08:01.

Prevent possible infinite recursion in ViewProperties

If each directory can have its own view properties, and loadting the
.directory file fails in a directory, we have to load the global view
properties. However, if we try to do this by changing the "global view
properties setting" and loading the view properties for the same
directory again, we might get an infinite recursion if changing the
setting fails.

We now force a loading of the global view properties by constructing a
new ViewProperties object with an empty URL.

Thanks to Kurt Hindenburg for helping to debug this issue (which was
only reproducible on MacOS).
