SIGSEGV error, ofBuffer&utf8 file, openFrameworks 0.9.2

Hey guys,

I try to read a utf8 text file into an ofBuffer with oF0.9.2. But the app crashes with a SIGSEGV error.

The output lines are correct. The error occurs in the end of the setup() method.

What is wrong here with this code?
My test device: LG G3 (Android 5.0, Locale:en-GB)

Crashing code:

void ofApp::setup() {
    ofLogNotice("ofApp") << "ofApp Setup";
    loadFile("utf8textfile.txt");
    ofLogNotice("ofApp") << "Setup finished";
}

void ofApp::update() {
    ofLogNotice("ofApp") << "ofApp Update";
}

void ofApp::draw() {
    ofLogNotice("ofApp") << "ofApp Draw";
}

void ofApp::loadFile(std::string filename) {
    ofFile file(filename);
    ofBuffer textfile(file);

    ofBuffer::Lines alllines = textfile.getLines();
    std::string firstline = alllines.begin().asString();
    ofLogNotice("ofApp") << "First Line:" << firstline;

    for (const std::string& currentline : alllines) {
        ofLogNotice("ofApp") << "Current Line:" << currentline;
    }

    ofLogNotice("ofApp") << "Reading file finished";
}


Logcat output:

Never mind, this did somehow start to work.
