I'm compiling Parole from master but I got a segmentation fault error on start. I found out that the offending commit is the following one: http://git.xfce.org/apps/parole/commit/?id=a2eed21e9c2c6404f7ee17d8bd9a722109220c92 Any revision before the one above is good. Any revision after the one above gives the segfault when starting Parole
Have you tried to compile in a clean git tree? Can't really reproduce your issue here.
(In reply to Simon Steinbeiss from comment #1) > Have you tried to compile in a clean git tree? > Yes, but the problem persist > Can't really reproduce your issue here. I don't know how can I help...in command line I only see (after a flash of the parole window): Segmentation fault (core dump created)
Ok, since the problem persists, please give us more information on your build system, so we can get closer to reproducing it. What version of Gtk are you building against? What version of gstreamer? What distribution? etc.
Hi, Please, attach a debug: In a terminal launch: $ gdb parole $ run ..and when crash type: bt ps: If your compile from git prepare the sources with: ./autogen.sh --enable-debug --prefix=/usr --libdir=/usr/lib64 (If not use x86_64 PC ignore --libdir=/usr/lib64) Also please: Test edit the file: HOME:/.config/xfce4/xfconf/xfce-perchannel-xml/parole.xml, and remove the lines: <property name="parole" type="empty"> <property name="plugins" type="string" value="/usr/lib64/parole-0/parole-mpris2.so"/> </property> This is to check that the mpri2 plugin is disabled.. Regards.
Ohhh... To check parole whitout any plugin you can use: $ parole --no-plugins So, ignore editing the file.. ;) But please.. try to get the debug and attach the result,

Thanks! now I can run parole again. I run these commands as suggested: > $ gdb parole > $ run Parole hung and from the command line I read this: TRACE[parole-pl-parser.c:795] parole_pl_parser_parse_from_file_by_extension(): playlist /home/prova/.local/share/xfce4/parole/auto-saved-playlist.m3u : ((ParolePlFormat) PAROLE_PL_FORMAT_M3U) So I deleted the above m3u file and parole is working again as expected. I don't know if this should classify as a bug... BTW thanks for the assistence!
Ok. Nice. =) Not seem related to the plugin mpris2 .. A tips.. When reports your next bug, please attach full backtrace.. It is useful to know how the code will behave before breaking.. =) The problem seems related to the opening of m3u playlists.. Open parole and test open any m3u playlist.
Created attachment 5317 Fix multiple free when open a bad m3u playlist Please test it. Not broke in the same position you backtrace, but I think this solve the bug.
Created attachment 5318 Fix open m3u playlists with all absolute paths D'Oh!.
