Oh, great. I found the cause and it's just a stupid typo in a debug message :(. If Geany is started without an existing configuration file, we log a message that the default TCP port for IPC is used (#2585). But in this log message I specified the wrong format specified for logging an integer and this leads to a crash.
This is actually independent from the Windows version, it only depends on the existence of a configuration file. Unfortunately, this does not explain why the "-2" installer worked for some people as the mentioned bug was included in it as well. -- You are receiving this because you are subscribed to this thread.
