为什么 btsync 核心转储在启动时出现“!directory.empty()”错误？

btsync当我在全新安装的 Fedora 21 上启动 BitTorrent Sync（ x64 版本）1.4.110 时，使用已知可在不同系统上工作的配置文件，我收到以下令人困惑的错误消息：

$ btsync --config /home/user/.btsync.conf
btsync: /mnt/jenkins/workspace/Build-Sync-x64/linux/breakpad/client/linux/handler/minidump_descriptor.h:55: google_breakpad::MinidumpDescriptor::MinidumpDescriptor(const string&): Assertion `!directory.empty()' failed.
Aborted (core dumped)

我的系统上没有安装 Jenkins。它看起来像是使用来自 BitTorrent 组织的发布工程构建服务器环境的符号编译的 BitTorrent Sync 版本。呵呵。

问题是什么？这是我的配置文件/home/user/.btsync.conf：

  "listening_port" : 0, // 0 - randomize port

问题出在以下文件夹的配置上：

  • /home/user/.btsync-- 保存 BitTorrent Sync 元数据的文件夹
  • /home/user/SyncFolder1-- 要同步的文件夹
  • /home/user/SyncFolder2-- 要同步的文件夹

启动时btsync，元数据文件夹/home/user/.btsync不存在。我创建了它，并确保我的用户帐户可以写入它。我还创建了两个同步文件夹。这些文件夹创建完成后，btsync正常启动：

$ btsync --config /home/user/.btsync.conf

BitTorrent Sync forked to background. pid = 15949. default port = 8888
